Has anyone tried to take a PM 2 blade and put it into a PM 3 handle?

I know that seems like a dumb question but hear me out. I have the PM2 in s110v and its very well loved. I got it when it first came out and this weekend I had it on the workbench sharpening it and I said to myself I turned the blade into a PM 3 with all the sharpening.

I wonder if it can be done for better blade : handle ratio? Just a thought..
 
I don’t think the PM2 blade would fit. Holding them up to each other I think the tip would protrude a decent bit and I think the edge would rest too close to the cutout for the lock.
 
Just for the heck of it, Ill try it right now and let you know as im curious myself.

If the pm2 blade doesnt fit the para 3. Maybe the para 3 blade will fit the other. Thatd be nice, PM2 ergos with a smaller blade.

Will post results shortly:thumbsup:

WHAT HAVE I DONE! This is the most unnatural abomination of a knife I have ever seen!! BURN IT!

Ok seriously, the blade is to big. Doesn’t close enough to even lock the detent, and as salty predicted the blade was to long.

Gonna try the pm3 blade in the pm2 next.


Btw, doing this with two Cruwear models as to minimize accidental edge damage. Incase people try this at home.

SO CLOSE. But no cigar..

The para3 activated the detent to early.
So close in design they’re PARTIALLY compatible. Only if you don’t plan on ever closing them.

I don’t recommend doing this at all though as it will definatly void your warranty. I nearly stripped the pm2s stop pin because the para 3 blade was to wide for it and closing it puts alot of pressure on the stop pin. Because of this I took the stop pin out in the picture.

So IF you added a detent in the right position and IF you have the know how to reverse engineer the entire thing, it could technically could be done after alot of tedious tinkering...

But realistically... no.. sorry.:(

Unless someone else has some ideas, I dont see it being possible from the factory. But HEY you could always regrind the pm2 blade to a smaller profile.:D
 
Paramilitary 2 blade in a para 3 handle sounds like a good idea for a fixed blade paramilitary, make it happen spyderco.
 
Whew...tip up carry on that first model would make for an interesting reach in the pocket! :eek::eek::eek:
 
Now if you were willing to regrind the tip to make it fit you could have a sheepsfoot style blade. Or any other custom style blade shape that you wanted.
 
Jeez now I feel bad! Sorry you almost stripped your stop pin. I just know that after sharpening my PM two so many times that the blade isn't as long as yours so I thought maybe it could be done. If I had a PM 3 I think I would try to regrind it to a sheepsfoot or reverse tonto. I hope your knives went back together fine.

Ah dont worry:D:thumbsup:, im a tinkerer, everything went back together just fine. Alot of people worry about taking apart spydercos but in my experience theyre VERY tough and durable knives to take apart.

I took a pair of pliers to the stop pin to force it to unscrew and put all back together. Perfect centering and just as smooth as before.

I did notice something that might be easier,, the pm2 and para 3 scales are almost identical. Instead of swapping the blades. you could modify pm2 scales to fit the para 3. This way you keep the correct detent.B328875B-E8CF-45C0-A612-3A6C6F21ECC9.jpeg 26A83E2C-AA39-41DC-A76A-15CB1F6D4F1C.jpeg

Here’s a para3 liner and a pm2 jade scale. You’d have to grind off the red on the steel liner for it to fit inside the scale. And the stop pin hole would have to be made a tiny bit larger to fit the para3 stop pin, I say try the pm2 stop pin first before you go grinding away at the scale.

Tip down carry screws don’t aline but who carry’s tip down anyway;) lol. Just kidding:rolleyes:

If I had some cheap beaters I’d try it myself but I can only have so much fun until something important breaks...

Glad it all went back together just fine! Going do to some tinkering with this because at the end of the day that para 2 in s110v that I have is spent, its full production and I can always get another. I have franken-millies why not a franken paramillie?

I own a para 3 with the interchangeable scales, will the paramilitary 2 scales fit my knife?

Hmm, I was recently searching for Para-series blade swap threads before today. I need to search harder or just wait for them to pop up like this one.:thumbsup:

I was silly to try the swap also.:p As stated above, the detent doesn't match up and the Para3 blade lockbar ledge needs just a little shave to work with the Para2 lockbar. I never measured the detent difference.

I would like to see longer Para3 lightweight handles or contoured handles. Maybe 4.60 inches❓
 
Give me a pm2 with a slightly longer blade spyderco!!!!
