Ensuring a Sharp Blade

Cutting those compliant washers required a really really sharp blade, which prompted me to put a new one in the cutter.

As a matter of course, I run a marker along the edge of all the new blades when I restock the utility cutter’s supply. The idea is that sometimes I can’t tell if the current blade’s been used; there’s nothing worse than sawing away at something delicate with a dull blade.

I generally use a blue marker, but the last time around the red one must have been closer to hand. I won’t make that mistake again…
