Bad idea. The cut-3 verbs, at least, are buggy. The identity I submitted,

can be rewritten:
; @:(<;._3~ $)
or
{.@:(];._3~ $)
but it loses the elegance (and therefore purpose) of the original. Similarly
for the razor:
> ];._3~ 0 ,: _1 + $
; @:(<;._3~ 0 ,: _1 + $)
I believe the other two blades cut the right way.
