knife handle pieces are called knife scales

anyone out there made knife handles

two schools of thought on it

one gets the scale very close to the final size of the handle part of
the knife blank then affix via epoxy
the contour is also done


the other just does a rough approximation with litte to no work on the
scales

for both cases one side is affixed and then hole are drilled as needed
then the second scale is affixed


seems to me the best approach is to get the scale as close as possible
to the final shape and size then affix to the knife blank

there does not seem to be any advantage to me for attaching the scales
in rough form

maybe there is some good reason but it is not clear
