I thought that the thumbstuds were likely just pressed in, and could be removed with a mallet.

I've been banging away at this thing for too long and there is no movement yet. It makes me wonder if they are glued in or if they screw together (or both?)

Any information or advice would be greatly appreciated - this would be my EDC if it weren't for those huge, useless thumbstuds!

Thanks!
 
The thumbstuds are press fit. They can be removed and the knife would be alright since they don't appear to function as blade stops.
 
Here's how I did it:
You want to squeeze the thumbstuds in a vise. Put a piece of leather on one side to prevent scratches. On the other side, use masking tape around the stud to protect the blade, and use about a 3/8" socket to encase the stud. By pressing this in a vise, the thumbstud will pop right into the socket. One side of the vise will be pushing on the stud while the other contacts only the socket.
If you want to put it back in, pop the thumbstud in a freezer for a bit to shrink it up.

These aren't my tricks, but they work like a charm. I did this on an 0300, but I believe it's the same for the 0200.
 
Thank you RevDevil - encouraged by your reinforcement, I got a bit more aggressive and the pin came out clean. I also decided to change my leverage - holding the blade end and laying the part of the blade where the pivot would be flat on a wood workbench. I hung the stud just over the edge and gave it a few extra solid strikes. All it needed was a little extra confidence.

Now to "knock back" the texture on the handle scales and make another alteration (rhymes with knave) and I'm all set.

Put some pics up when you wrap it up. W'd love to see the changes.

Can't imagine that worked too well on the 0300. I'm guessing that is why you know how to install the stud, too. ;)
 
Ah took me a minute to realize what you meant! The trick works great but the 0300 is much better with bladestops. :-)
I removed mine because there seemed to be rust forming under there. False alarm but I learned a new skill!
