84mm and 91mm compatability

[Helvetica Bold]

Anyone know if the springs in an 84mm knife will work with the blades from a 91mm (if they are suitably shortened) without any modification to the tang end and if they are still 2.4mm thick?

May sound a strange question but I have a couple of broken 91mm blades (main and small) I’d like to reshape and build back into a walker or ‘my first’ frame perhaps.

Diameter of brass pivot for blade is 2.2 mm on 84mm sak,and 2.5 mm on 91mm models. So you need to make a some bush or drilled bigger hole for use 2.5 pin with blade from 91mm model.

Ah, I knew there would be something. Very useful info, thank you.

What 91mm tools did you want to put on an 84?  Different tools require different springs.  I don’t know if the pin size is going to matter to much considering Vic uses a 93mm e-blade with the 3mm hole on the 91mm and 84mm models.

I've used the nail file from a 84mm knife on a 91mm backspring with no issues, so for the small blade at least there should be no problem.

It’s the main and small blades. Bother are much shorter than original where I have ground new blade shapes out of the broken ones. The main blade is 2.4mm wide old one. I was thinking of putting them in the back layer and making a stockman ‘victoristock’ type affair...but with a saw in between the blades!
