I just may have come across THE SOLUTION to those who LOVE CRK, but HATE the thumb stud(s). Or just maybe the start of the beginning, that may or may not lead to the possible solution ...and other misc. nonsensical psycho babble.

🤔So after experiencing Sebenza thumb, I researched and read so many discussions and opinions. I tried all the suggestions (yes, even proper technique and hanging upside down with my tongue sticking out sideways). There's gotta be something else besides grinding them down or drilling the thumb studs out and replacing them.

My perspective on this is a little different I think. I understand we all have different opinions and views, but dispite hating that thumbstud, I want to use and keep my CRK. Quite frequently, I open and close it all day long to cut things and I'd like the thumbstud to be more comfortable.

With a special education background, I believe in modifing and adapting things for people who need it. Growing older, accidents, medical/hand/finger conditions, and ESPECIALLY uncomfortable thumbstuds (for some, NOT ALL) shouldn't keep me or anyone else from loving ALL and EVERYTHING about CRK. So how can I modify it without possibly damaging it, messing it up the knife and the warranty, getting frustrated, or paying more money to get aftermarket studs. I know Abraham Lincoln said you can't make everyone happy all the time, but I wish there was an "adapter" or something that's offered for those customers who need or want a different thumbstud for whatever reason. Since I 3D print Marvel & DC Helmets, Masks, Thor's Hammer, etc. I wondered if I could print an adapter or something - adding something semi-permanent for comfort and ease, rather than taking away, like cutting, grinding, or drilling.

THE SOLUTION: I put a drop of UV Clear Resin on top of the thumbstud, just to see if that would make it less "pointy". After some trial and error and mis-drips, I figured out how to put a small "bubble" on the tip of the thumb stud and UV light it by controling the amount, swirlling, dabbing, and then flipping it over while under the UV light.

Here's a picture of what it looks like now.

Annnnnnnnd .... IT WORKS! It is comfortable for me now. Just adjust the size, shape, of the drop(s) per YOUR personal preference, or maybe someone can design and CAD a 3D hollow mold or cavity that forms a certain shape and size that will make the current thumbstub into the BEST ONE EVER, then fill it, place the knife on it so the stud sits in the resin. Then zap it, slight sand maybe. Oh, and if you want to sell it - just remove the resin first. Thoughts?

Nevermind, it just hit me that a crystal clear, pressure-fitting silicone cap probably would work better. Anyone want to help me design or figure this out? Anyone? Bueller?

I can't see a drop of resin being a permanent solution. I will say the crk thumbstud design makes me blink repeatedly while questioning who the hell thought it was a good idea. Easy fix to swap thumbstuds though and the rest of the knife are near perfect.

I personally like the thumbstuds on the knives but totally agree that a drop of resin isn't any kind of solution.
 
I have used a short piece of heat-shrink tubing on a few different thumbstuds (not CRK though). Some thumbstuds retain the tubing, but you can also use a spot of super glue to hold it on. Superglue dissolves in acetone.
 
Replacing my (single) thumbstud didn't required neither grinding nor drilling, just a right size allen bit and hammer.
I think he's talking about double lugs, I had to grind, drill and punch for my inkosi.

My solution- Put it back in the box and leave it there, then get something better that doesn't have that godawful thumb stud.

Interesting idea. I wonder if electrical shrink tubing would work.
Great thought! I'll try what I have from Harbor Freight and see what happens. Anyone else want to experiment and share your results, thoughts, and conclusions on the "Shrink Tube Thumbstud Comforting Experiment" (STTCE)?
 
I did a very similar thing with an Enlan knife that had and cross-bar lock that was made up of a nut and bolt, and the nut could be removed using a spanner. Naturally, the groove left for the spanner was sharp, so I cleaned it up with acetone and put a drop of superglue on each side, achieving the same effect. This also made the cross-bar stick out a bit more which also aided in working the mechanism. It has a botched heat treat (if any) so I just beat on it relentlessly, batoning, throwing, opening beer... surprisingly the superglue held on without a problem.
 
Yeah that's a cool low tech solution for people who don't want to bother with tinker work, while everyone here loves knives, not everyone has a specialized toolbox garage on demand. But there is merit to having tools around if one is able to do basic DIY stuff..
