Not sure what your comeback meant, but for me, after doing a teeny bit of drilling & sanding on antler, the stench was overpowering, so to see all those grindings, ringlets for tying on stuff, it just amazes me and it's so totally white! I can only imagine that takes some tedious bit of working...
A Porsche mechanic used to tease when we'd chat about boring out the cylinders for his racing car, he'd say he'd bore it out till he punched thru the water jacket then back off 10 thousands...

I have the same concept about grinding cow horns like that!
