Ground Troop 35 (GT35) Design Discussion


Lots of questions have been pouring in about the BLOCK lock and other design features of the GT35.

Feel free to ask questions, and I'll do my best to answer as many as possible.

Here are a few discussion points to get us started.

The GT35 is a remarkable folder. The handle is EXTREMELY thin at only 1/4" (.250).

Combine this with an overall weight of approximately 2.8 ounces, and it is ridiculously thin and light.

I have been carrying one in my shirt pocket for over a year now, and I have to feel my pocket to see if it is in there!!!

If you've been looking for your favorite EDC Folder, this is the way to go!

Our goal with the GT35 was to make the strongest, lightweight, and stain-resistant folder ever built.

I believe that we have achieved that goal.

In our lock-strength tests, nothing in this size range has even come close so far.

The GT35 was designed for the battlefield, where every ounce counts and toughness, ease of resharpening, and stain resistance are of utmost importance.

When used on AEB-L, our deep cryogenic, INFI-type heat treat protocol has yielded very impressive results thus far.

The finely ground blade is easy to keep sharp in the field without having to completely re-grind it.

The steel choice is important in this design, as it plays a major role in the strength of the lock.

BC AEB-L has proven to be up to the task at hand.

Why no talon hole? Putting a "talon hole" in the handle could put your lock mechanism at risk, depending on location and size.

Most importantly, however, is understanding that our Trademarked talon hole is specifically noted to be in the rearward portion of the "Blade" and not in the handle itself.

The main difference between our BLOCK lock and a crossbar lock is that our locking block rests on the spine of the knife as opposed to spanning both handle slabs, like most other crossbar locks.

Our thumb button release on the side of the GT35 will be shorter and of a lower profile than the one pictured by nearly .040"

The CNC-machined solid billet of 6AL4V offers much higher strength than typical "panel" folders because the handles are not dependent on micro-screws for strength and rigidity.

Why is it called the BLOCK lock? Once you see the inner workings of this folder, you will quickly note that a large block of hardened stainless steel (58-60 RC) is moved forward by a compression spring, not an omega spring, to ensure the proper seating of the lock block.

We are having custom ball bearings made for this model and will post pics once they are available.

Someone mentioned the "Double click" sound of the BLOCK lock. It reminds me of the beautiful sound made by the original Colt Single Actions of years gone by.

You can eliminate the sound by holding the lock button back during deployment. But, if you're like me, you will fall in love with the sound of this bank vault-like engagement!

BC AEB-L what is the BC stand for? And is it different from the AEB-L from SYKCO Scrapivore? Is it American AEB-L? Jw for posterity
 
Hi Bossman,

I'm curious if you would consider making a "Heavy Heart" type folder with INFI and washers in the future - or more future folders in general.

I do not want to miss out but much prefer washers than bearings and also would love to get some folding INFI.

Cheers!
 
Thanks for clearing up the question of the fore-ward guard holes. :thumbsup:

Two questions for you please, thanks!

Question #1: Will the GT35 be easily serviceable & field strippable by the user?

Question #2: BLOCK .... is it an acronym?

What keeps the pocket clip from spinning other than tension between the screw and smooth surface of the handle?

Is the knife easy to field disassemble and reassemble?

It is a "D" shaped hole like the one used in our pivot to keep it in place.

The "D" shaped hole extends through the handle and through the clip as well.

The "D" shape on the shaft of the screw locks in and cannot rotate.

Yes, that has most of the key points. 👍

Jerry, congratulations on bringing the Busse folder to fruition. What a tremendous accomplishment in the annals of the Busse brand this represents. I love the choice of the blade steel, I love that the blade has been optimized for slicing and I think the blade length is totally reasonable. I fully expect that the ingenuity and long term reliability of the Block Lock design will be borne out over time as these folders work their way into the hands of throngs of your eager customers.

Looking into your crystal ball for just a moment, would you put the likelihood of a follow on version becoming available at some point in the future, particularly one that would be appreciably heavier and with a thicker handle, above or below the 50% mark?
 
Ordered, can't wait to check it out and do some breakdowns videos on it and similar mechanisms. Designwise, it reminds me of an upscale/overbuilt/more user-friendly version of the Cold Steel "Pocket Bushman" and Ram Safe Lock🤔 Are those dual stop pins for lockbar to wedge against?
