Bore da

Rwyf wrthi'n cyfieithu
darn o waith ar wahanol fathau o gyllyll a llafnau.
Nid wyf yn gallu meddwl sut i gyfieithu 'taper-ground
blades' a 'hollow-ground blades':
Taper-ground
blades - This is where the whole blade is machine ground
and shaped from the back to the cutting edge forming a
taper. The process produces a well-designed blade with
an efficient cutting edge that can be easily
sharpened.
Hollow-ground
blades - Cheaper knives are made by machine grinding the
cutting edge along the bottom of the blade. Unlike
taper-grinding where the whole blade is tapered to a cutting
edge, the cutting edge of a hollow-ground blade is formed
only at the edge of the blade.
Buaswn yn gwerthfawrogi
eich awgrymiadau - nid oeddwn yn sylweddoli bod yna cymaint
o wahanol fathau o gyllyll!
Diolch
Ceri :-)
