For the price they want for those Keencuts . . . I'll stick to the old X-acto and a straight edge :LOL:
One would think that because of their expense, that the Keencuts are not worth it.
But they can rip through coroplast and other substrates 5-10 times as fast as mucking about with a ruler and knife.
The Keencuts have a non-slip bottom so they simply will not move (like a ruler will) once they're positioned.
I have a 104" Keencut and use it on a 5' x 10' cutting mat/table and can get some serious cutting done with that.
If I recall, it was over a grand, but in the past five years, it has way more than paid for itself in time saved.
