Key cutting wheel shape

[WOT]

Why is it some machines have a dual bevel wheel with a cutting surface profile that looks like:

\/ while some have a single bevel edge like |/ (like my Ilco Unican) ?

I find the lack of bevel on both sides makes code cutting by depth keys way more complicated.

You pretty much answered your own question.. a code cutting blade is for cuttting the valleys of the key correcty .. a duplicating blade is for duplicating a key.. some keys have a " flat" or square 1st cut, a flat faced cutter will have no problem duplicating either.

This depends mainly on the cutter. Some cutters are intended to cut by progressing from side to side while at the intended depth. This is mainly seen on duplicators (but you can still code cut with depth/space keys). Other cutters are intended to cut by "stamping" down each cut at a stationary position; both fore and aft slopes are shaped by the wheel alone, and not a template key.

PS. I haven't seen a duplicator wheel with a cutting edge on both sides. But if such wheels exist, I expect that they cost more. So to answer the question of Why? To save money.

A flat side was necessary because many of the early wafer locks had a very short distance from the shoulder to the first cut. Several of these keys did have cut straight down and our Borkey key machine could not make this first cut because it had a bevel on the back side.
