PST OHO knife

A new project I am working on.

Some teaser first.  :D :D

Some of you may find that it look familiar. Make a guess. ;)

A detail How-tos coming later tonight.

Is the part from a Gerber?

Ok. Here goes.

First I would say its a Knife attachment mod, rather than modifying anything on a PST. Nothing is changed other than one screw. This knife is held by a liner lock, Its seems to be sturdy enough. No detectable vertical or horizontal play. Worthy enough to put it on a PST.

Lets call this the PST Knife Attachment. aka PSTKA ... Lame name, I know...  :whistle:

Its a detachable knife part that came from a Irwin Vise Grip. To be completely honest, I accidentally bought it off Amazon and only realize it when I received a Shipped! notification. Ironically, the one thing that really put me off was in fact, the knife. Its positioned in a laughable position on the vise grip.. So, the moment I received it, the knife was the first thing that came off. That, was more than half a year ago.. Couldn't be happier that I didn't trash it immediately.

The said donor - Iwrin Vise grip 5in.


This is the very initial stage during the fitting. To my amazement and relief, the 2 holes actually align perfectly. I really hate to have to drill as I lack the proper tools. The only little problem is that the pivot screw on the knife is 5mm I think and the PST is 4.5mm dia. Filing it down to proper dia was rather easy, had to cut down on a little length too. Fitting it on a spare PST frame, just some corners that need to file away. Other than that the whole attachment was a really nice fit.



As you can see, the frame was painted in black, didnt like it. It just screamed CHEAP. I removed it by paint remover. NAsty stuff, use protection! Followed by sanding it down. Result was a satisfying brushed metal finish.


Next up, I want to reprofile the knife and touch up on the blade.


Reprofiling the spine was easy with a bench grinder.


Giving it a real cutting edge was not..the bevel was so thick that its more like a toy knife... Took me quite a while to give it a proper edge.
Original edge

After worked on. The serrated part was really irritating. Arghhh! Need more work on that some time later..


Final product. Its really just a attachment that can be used on any PSTs. Another lucky find by yours truly..  ;)




Initial post, I had it on one of my acid washed PST. Now, Its on one of my polished ( half baked :facepalm:) PST. I think, It looked nicer.  :D

Below, I will just flood it with pictures. Enjoy  8)












Finally, a last pic with its Donor Buddy.  ;)


Cheers!
Sam

Thanks for the pics, it really looks awesome. That's basically what LM did with the PST and we got the Wave.

It looks like the frame and blade can be removed from the vise grip and you could use both independently.
Maybe Irwin will release the knife on its own. Maybe add a pocket clip with a notch to open bottles as well.  :whistle:

You should give it a try. You will see how well it fits. The blade is total crap though. It's really thick. I am still having trouble getting it's properly sharp.

An Idea sprung. Another hybrid on the way.

Still in prototype stage. Major challenge is the pivot for the knife. Solved!





Will be some time before a proper thread on this comes up.. Minor change need to be done. At the moment, its a fully functional knife with a perfect lockup. ;)
