Your hands and fingers will hate you for using that.I would think this would work also. About $3 and some replaceable blades.

Razor blades are a bit too flimsy, and will easily dig into the slate... Utility blades are better.I would think this would work also. About $3 and some replaceable blades.

I used to use that style, but it was cumbersome to change the blades.Get some decent utility blades (Personna is a great brand) and one of these https://www.amazon.com/dp/B0083HXVDA
I just got that same one a few weeks ago and it's nice and heavy duty. Some of these things will come apart where the handle meets the blade holder.
Looks good! Thanks for the tip. I will try one out for sure.This style is much easier to use. Especially, once you sand the protrusions off from the blade surface.
