It looks to me as though that key MAY be for a
wafer lock, in which case, I would not try to bump.
Also, If it is for a pin tumbler lock, what happens if
you are trying to bump a 9cut pin?
I would probably shave a tiny bit off the cut depths because it is quite a popular belief that 10-10-10
keys are better.
Having said that, I have never bothered to try bumping.
I guess though, from some of the pictures that I
have seen of bump keys, that aparrently work and
considering that the depth and spacing was
professionally done, it seems nice.
