Single edge safe maker or keepers

[shinyedges]

Been looking at these safe maker and keepers, is the safe keeper 3 the only variant that is single edge?

Yes, the Safe Keeper III is the only one with a single edge.

Damn it, I might just get a larger keeper or maker and grind one side flat so it's legal.

And thank you.
