I've a knife that's got a pen blade that needs to go
its snapped of and the void makes the main blade unstable
I've no tools so to speak of but happy to pick a few up
any suggestions on the safest way to knock out the pins so I can retain the rest of the knife and reassemble it
this will be my first real project so be gentle

Hi Corso,
Dale posted one of his techniques over in the tutorial section and it’s one way way to do it,
viewtopic.php?f=38&t=5236
And there’s another complete disassembly procedure posted by him too if the above method isn’t right for you.

If you are planning on re-using the covers, I would be leery of using the razor blade method of splitting the pins. I typically use that method only if I am NOT re-using the covers. IMO, there is a good chance of cracking the material at the center pin by stressing the pin there with the razor blade.
When I want to retain the covers for re-use, then I usually drill out the heads of the pins and tap them out. Of course, there is always the chance of doing damage to the covers with a straying drill bit, but I feel more comfortable with this method.
Either method, good luck and go slow!

Good point Glennbad!
I usually use a small carbide ball burr to remove the head on the center pin and tap that one out then use the razor blade method to remove the bolster and end pins.
You can also use the small ball burr on the bolster pins and then drill them out. The ball burr gives a nice concave surface to help keep the drill bit from wandering (it’s not 100% but it seems to help me when I use the drill bit method)

See, you learn something new every day. I would have never thought to use a burr to cup that pin first. Thanks for the tip!

I normally use a small burr in a dremel or foredom to remove the head on the center pin on both sides of the knife, then split the knife apart with a razor blade.

So as an update
I now have a single layer Joseph Rodger pen knife
I will be carrying this alot now
Dales trick worked great on the pivot pin but the rocker pin wasn't going to cut. Ended up filing off the pin head and tapping it out with a hammer

Glad to hear that you got it!
Now, however, we need pictures.
NEED them, not want them!

Glenn made a good point about the razor blade method, it can cause damage to the handles. I don't use that method if I am trying to salvage the handles, especially old bone or old stag handles, they can be very fragile. In that case I drill the pins out or use a Foredom.

Appreciate the advice
I wasn't sure I wanted to keep the scales so wasn't too worried
I was however careful and since the survived i decided to use the,
This was destined for the sales as the little pen blades sharp corner would rub when I tried to use the main blade
its a keeper now...
the only think I need to sort is the final rub down of the main pin- flutted bolsters are making it tricky
