I picked up some older arrows not long ago....yard sale, $1 for all 4 of them. Anyway, looking at the arrows as of late, I noticed something strange - 1 of the arrows has alot going on ....a continuos taper from 23/64 at the point to 5/16 at the nock. The arrow is straight fletched and (this is the wierd part, to me!) these fletches are in a channel that was cut or routed into the shaft! Ive never seen this before! Was this common in arrows of yesterday? The arrow seems old but, is very well made.
