Custom scales for this knife are extremely common to me!

I make custom scales for all different kinds of BM Axis knives.
With the Griptilian series and the 710 series being in the highest demand.
Making custom scales for a knife with an Axis lock does require more work.
There is definitely a lot more chances to screw it up.
Especially with nested liners & an Axis lock mechanism....Mini-Grip/Ritter.
But, it's like ridding a bike.
While learning how to do it................ If you're not falling down once and a while, than you're not trying anything new.
And
Once you learn how............. You never forget.
Your original question was for
"metal scales", that my friend is a whole different thing.
