DMTD3EFC 3-inch Dia-Sharp Sharpener, Credit Card Sized- Extra-Fine, Fine and Coarse Diamond -Set of 3

Q: How brittle are these? I want to put one in my edc pouch that rides around in my cargo pocket. Will they snap easily if bumped or flexed?

I don't think there is any danger of snapping the Dia-Sharp card by accident (or on purpose, for that matter). The substrate appears to be steel, about 1.5x the thickness of a credit card, with the finishing surface diamond-impregnated.

Q: Has anybody tried cutting these in half....to potentially double your usage time?.otherwise, i find the middle doesnt get used, just the edges. ThankS

Never have tried to cut them in half. Haven't experienced your problem with wear either. love these little stones. They do wear out though.

Q: Is there any abrasive on the card edges?

Just had a look at mine--nope, no abrasive on the edge--the cards are really thin, so I don't there really could be, anyway.

Q: Can the cards be modified in any way? Like cutting down to size or drilling holes through them to attach to a lanyard or camping bag?

They are just metal cards with an adhesive matrix that diamond chips are embedded into. You can cut or drill them as you want, but be careful so as to not knock the diamond chips loose from the card.
