How to Compare the Vulcan / V2 to Torsion Spring Grippers

There has been a decent amount of information put out regarding the strength levels and the ratings of Torsion Spring Grippers like the IronMind Captains of Crush and other similar grippers. With the development of the RGC device which is able to rate these grippers by testing how much weight it takes to touch the handles together, we are now able to compare grippers from different companies, despite the different numbering systems that the companies use.

In the following video, I talk at length about the results that we have found from rating grippers using the RGC device.

However, with all of the information out there for TSG ratings, where this type of information has fallen short is with the Vulcan V2 Gripper, and many people want to understand this better. They want to know where the various levels of the Vulcan V2 Gripper stand against the Torsion Spring Grippers.

Below is a chart that was put together by Richard MacLean. It shows strength ratings of the springs on the Vulcan V2 Gripper across various settings. But, before you check it out, you must understand a few important points…

Important Details about Gripper Strength Ratings

1. All springs vary somewhat. Some springs can be just naturally harder than others, even springs from the same batches. Frequent use, stretching the springs out on the hardest settings, and poor care or irresponsible use can all have an effect, but for the most part these numbers can be used to judge what you have as well.

2. Torsion Springs (regular hand grippers) act differently from Coil Springs (Vulcan). With Torsion Spring Grippers, when you squeeze them, there is also some twisting that can take place, so you have to redirect force in order to make the handles move together. With Coil Springs, they primarily just stretch and lengthen. The point is, the springs act differently, so you have to take that into consideration as well.

What is Included in the Table

So, let me explain exactly what the table below shows. In Column A, you will see the ratings results from Richard M. on a fresh spring with very few closes on it. He tested the spring all the way out to Level 24. In Column B, he tested the same spring again, this time going all the way to 27.

You will see that the strength levels dropped at almost all of the settings on the second time through, most likely because going out to Level 24 weakened the spring somewhat, dropping the numbers.

This spring weakening (to this degree) will most likely not take place in your training with the Vulcan or V2 because there will be no need for you to go out to Level 24. Also, if you do go out to Level 24, you won’t be holding it there for an extended time, which may have taken place during the strength rating process. Upon writing this article, I know of NO ONE in the world who has ever closed this Gripper at Level 24.

Long story short, to get an estimate of the strength level of your Vulcan and Spring, provided you have not use the spring way out on the ends and done foot stomping or chest crushing, and as long as you aren’t hanging weight off the spring to deliberately weaken it, your spring is probably closer to the first run of numbers that Richard produced.

Also, take note that Richard used a Silver Black Dipped Spring on his V2, which has been rated equal in strength to the Black Spring and the Gold Spring. So if you have those springs, you can bank on very similar strength ratings.

                       L27=197.4 |

Big thanks to Richard MacLean for not only producing these results, but also for letting me post the results here.

Comparing Vulcan V2 Ratings to Torsion Spring Grippers

Unfortunately, if you are looking to use those numbers as direct comparisons to Torsion Spring Grippers, then you are out of luck. With the Vulcan, the force at close reads out much lower than with a torsion spring gripper.

For instance, the bolded numbers above are the ranges that I usually equate to the feel of a #3 Gripper, levels 13 to 15, depending on the stiffness of the spring.

David Horne has pointed out in many cases I have read that with the Black, Gold, and Silver Black Dip spring, level 13 is right near the difficulty of a #3, when the spring is fairly new.

Now, if you have used the same spring on a Vulcan, a V2, and a Wrist Developer and do one of those movements every workout, then the strength of the spring might be a bit reduced due to all the use, and so the squeeze may not feel like #3 strength until you get up around Level 15.

Either way, that range is what you want to shoot for if you are gearing up for closing the #3.

Other Comparisons and Estimates

We can also assume that a Level 22 is also pretty close to a #4 Gripper close. This is based on the fact that I have seen video of Paul Knight closing both a #4 and Vulcan Level 22. Harder #4′s would be up in the range of Level 24 or higher. These are just my personal estimations.

David Horne lists the following estimates on his site:

• #2 = Level 7-8
• #2.5 = Level 10-11
• #3 = Level 13-14
• #3.5 = Level 17-18
• #4 = Level 20-21

Remember, these estimations are for the Black, Gold, or Silver Black Dip springs. There may indeed be other springs that are equal in strength that I am not familiar with. I am just going on my own experience with them.

In addition, if you do not have IronMind CoC Grippers, in order to estimate where your Vulcan closing strength lies against Torsion Spring Grippers, you can use the estimates above and compare them against results taken from testing done with other similar Grippers.

For instance, if you know that your Beef Builder Elite Gripper rates at 159 on an RGC, then that is slightly above most #3 grippers, which these days come out around high 140′s and low 150′s. A 159 TSG would probably be around a Level 16 on a Vulcan (estimating).

I hope this post has been helpful for you. If you are in need of any further explanation, please let me know – since this topic has been such a source of confusion for so many people, I would be glad to go back and add in details where they are needed. Please just leave a comment below.

Thanks and all the best in your training.

Various Blobs in Richard Sorin’s personal collection. (L to R) The first Blob, The first Blob’s sister head, and the Blue Blob.

Fatman Blobs & Next Generation Blobs

As I have covered here many times in other posts, the Blob is one of the most exciting types of Block Weights available with which to train.

Popularity + Scarcity = Big $$$

Their popularity growth, combined with their scarcity, has generated some pretty amazing prices in recent transactions that I have become aware of.

Unfortunately, any time you have something with a training benefit, and a collector’s value, there will be people who will do one of the following things:

1. They will claim to have something they don’t and try to charge too much money on purpose

2. They will think they have something they actually don’t and charge too much money by accident

I have heard of cases where people were told they would be buying a Fatman Blob, but in actuality, they end up with a Next Generation Blob and are extremely pissed off.

I have also been asked countless times what the difference is between a Fatman Blob and a Next Generation Blob. So I put together this short and simple video that will show you the easiest way to tell whether or not the dumbbell in question is an old York that will produce Fatman Blobs or Next Generation Blobs.

How to Tell the Difference Between Fatman and Next Generation Blobs

This is the absolute quickest way to tell if a York Dumbbell is the original style (Fatman) or the Next Generation variety – the USA stamping on the York head. If you see it, it’s NOT a FATMAN!. If it is blank on that side, the it is a FATMAN.

The numbered side means nothing. The number side will not have the stamp, so if you are thinking of making a purchase, this is the quickest way to tell.

Aside from the USA stamp, there is also a difference in handle size that if you have a micrometer, you can check for. The Original Style Fatman York Dumbbells will have a handle that is roughly 1/16″ smaller in diameter than the Next Generation Blobs. So, if you have a tape measure handy, you can check this way as well.

If you have no tape measure, and the York side is not present, it is going to be tough for you to tell which type of Blob it is. The only other way to really go about doing it is by feel. On the Next Generation Blob, the side of the Blob that had the handle in it will be a bit flatter than that same side of a Fatman. This is why the Original Style Blob is called the Fatman, because it bulges more than the Next Generation Blob.

There is also an even more rare type of Blob out there, called the Blue Blob. I have only ever seen one of these at Richard Sorin’s Srinex Facility. It is an obvious blue shade, so there is no reason to turn this dumbbell over to look.

So, in review, this is what to look for:

1. On the York side, if it says USA on the bottom, it is Next generation. No USA, then it is an Original-style Fatman Blob.

2. If the handle side is slightly smaller than another Blob of the same weight, it is most likely the Fatman variety.

3. If the handle side of the head bulges more, the it is a Fatman.

I hope this has been helpful for you to tell exactly what it is you might have, and also in case you are posed with a possible purchase sometime down the line.

Got a Blob?

Got a Fatman, Blue Blob, or Next generation Blob? I want to do a post down the line called Blobs Around the World! Get a picture of yourself lifting the Blob, just holding the Blob, your Blob collection, etc., and I will post it up here.

Send me your pictures by February 28th and I will have the post up the week of March 5th. Also include a 100-word description or so telling us how you got your Blob and any other cool training stories.

Thanks and all the best in your training.

This is a video I shot as part of an article for my buddy, Murph, recently on what to do with lighter grippers you might have laying around, especially if you have family members like I do, that don’t quite understand what it is you do in your Grip Training.

Check it out.

Taking requests for upcoming videos – anybody got anything they want to see?

Thanks,

I am working with David Horne on getting another order of his famous and popular V2-Vulcan Grippers and Wrist Developers shipped here to the United States.

Since it has worked out so smoothly in the past, I will be doing this on a pre-order basis. Just let me know that you are interested in a Vulcan V2, Wrist Developer, Thumb Screws, or extra Springs by either leaving a comment below or emailing me.

If you are not familiar with these pieces of equipment, let me tell you a bit about them.

Here is a video I put up, yesterday.

Here is some additional information on the many pieces of equipment I will be getting in from World of Grip.

Vulcan Gripper (V2)

The Vulcan Gripper is David Horne’s “nutcracker” style hand gripper that is adjustable over a variety of strength levels. It has two loading arms with notches which hold a coil spring. The spring can be adjusted up and down in order to adjust the difficulty level.

Vulcan V2 – January 2012, World of Grip

The Vulcan was re-designed late last year and is being sold as the V2. The new design has a slightly wider handle setting than the original, but it also is a much more attractive piece now, as some of the visual flaws of the first version have been removed and eliminated.

The V2 comes with a Crom spring, which is a chromed spring. The Crom spring is 3 levels harder than the silver/black dip spring that was shipped with Vulcans last year.

Other springs, white and orange, can be ordered. The white springs are very light, while the Orange Springs are a more moderate strength level. Springs from the V2 and original Vulcan will work with one another.

Wrist Developer

The Wrist Developer is a device that is designed to mimic and strengthen the movement pattern of Reverse Style Bending.

It uses a similar loading structure as the Vulcan / V2, with two bars and same dimensions. The Wrist Developer comes with its own Crom Spring. Springs are interchangeable between the Wrist Developer and V2.

Thumb Screws

Thumb Screws are attachments that go onto the handles of the Vulcan Gripper in order to train dynamic pinch, similar to a lever-action pinch training device.

If you are interested in picking up one or more of these items, please post a comment here or email me through the contact form.

Thanks,

Jedd
