There is no reason it won't if you buy new scales, there are plenty of videos on YouTube how to change scales btw.Your old red scales won't probably be as tight if you use them for another knife even though you gently removed them.
It’s a relatively easy job to do - I use a vice with rubber jaw covers to ensure the new scales go on snugly and evenly, but it’s not essential! Good luck!
I’m looking at possibly changing the scales on my new Swisschamp from red to black. Not because they are worn out but just because it looks pretty cool in black. All my other SAKS have been the traditional red. Now my question is if I swap them out, will the fit be the same as original? Now mine are nice and tight and no play. Not sure if I try and remove the old ones and snap on so new ones that it’ll be the same fit and finish.
