Zapote Long Pen Blank (5 Pack) - 3/4"

This is nicely cut on all 4 sides and clearly marked.

These look like cast brick. They feel like a sharpening or honing stone. I haven't had the time to cut one yet, but it definitely looks like carbide would be required. If you can't cut it you can use it to sharpen HS steel tools. I'm looking forward to see how it cuts and finishes. Very tight grain. Worth taking a look at.
