Bill,
Yep. Carried/used an EZ-Lap since they made dirt but the folding 2-sided DMTs are what I carry now. Everyone in the family carries a coarse-fine combo (blue-red) except me (I get to carry extra junk). I carry a black-blue and a red-green. The EZ-Laps are now at home in the consoles of my 4x4 and my eldest son's 4x4.
BTW, thanks for the tip about matrix break-down - I had suspected that, so now I know...
Made up some cheap pocket hones for scouts with wet-or-dry carborundum paper glued to a piece of aluminum (two grits on opposite faces). Used 3M #77 spray adhesive. The peel-and-stick mylar-backed diamond "paper" would be better, I'm sure, but I return to the word "cheap"... These work great for the scouts to keep an edge re-touched... and the clever ones have realized that they are sure-fire striking surfaces for kitchen matches.
Speaking of scouts - gotta run - off to camp to do weekend survival training for a bunch.
Tell us more about how you go about this, please!
Regards,
Tom
