Well as some of you know I am very OCD about certain things. Having the tip of a knife sunken well into the handle is one of them. I decided to void my warranty and make mine the way I like it.

The UK Pen Knife came apart much easier than I thought it would and it was easy to put back together. I just had to be patient, work slow, and have good lighting.

I thought you might like to see the pictures.

I would also like to suggest that maybe Sal and crew consider making a small improvement change to the UKPK for the future. I would like to see this hump ground down a tad more from the factory. I understand it's probably laser cut or stamped (I would bet laser cut) but I think if it's laser cut it wouldn't be a huge deal to change that hump where the choil sits when the knife is closed. :) Just a suggestion.

On to the pics....in order.

Here is where you can see how much more the tip sits into the handle now. I love it. You can even see that if the blade were about 1/8" longer that it would make the tip covered even more by the handle bump at the butt end.

This shows where I removed material a little bit to sink the tip into the handle.

All back together.

nice idea.

would it have been simpler to remove material from the choil rather than disassemble?
 
My UKPKs operate fine. The blade or tip has never been an issue, it's flawless.
Good job on the mod though, if it works for ya, that's all that matters.

Depends. I didn't want to change the look of the choil.

In addition to that I think the blade steel is harder than the backspring. I say this because I tried to file the choil of a foliage green UKPK I had. It was futile. It basically took chunks off my file. :D Plus with the disassembly at least my mod is pretty much unseen. :)

of course, heat treated blade steel vs. soft(ish) backspring. :foot:


makes sense, good work.
 
GREAT WORK David!!! IMO that makes a big difference! I think the UKPK is pretty much the perfect, simple knife. I thought something like this would be a great option... glad to see that it WORKS! I just may have to give the UKPK another shot and do the same thing. If I do, I might even take off a bit more... Again... FANTASTIC work!
 
Hey Arch,

Thanks man. Much love brother. I still dig all your vids. I do agree also, that I may want to remove just a little more and get that tip extra buried. ;)

Have a good one bro. :thumbup:
