I'd say more for the wood workers than metal folk,but alls fair?
My two favorite ferruls are 1/2" EMT cut to length and .45 ACP cases.
The EMT gets used on all our file handles.Have about a dz, "working" files in both wood shop and metal(hundreds in inventory).We turn the handles to a very specific,slightly reverse taper.... Look at your finger lengths.They get shorter going from fore to pinky.File handles typically are "ball ended".Slight reverse taper is oval vs ball end in profile.With ours being not a perfect oval,little bigger towards the file/rasp end.
Used to have a profile card around that gave profile pattern and ferrule dimensions scribbled on it,but have turned so many just bust'm out.The EMT gets cut with a tubing cutter,not a saw.
Next is the .45 cases.These get gauldang "pretty".Same concept but on a 3/4 scale vs rasp handles.Same nice quality BW,Maple,Hickory hdwd but scaled down as handles for "Allen" wrenches.Same slight reverse taper.But now a brass ferrul.The "trick" is cutting off a long legged wrench ON the short leg.This cutoff pce BTW,gets used in 1/4" drive sockets as well,SC drivers....
Now you have the Allen wrench with a just a slight bend on the leg.They get cut with die grinders(or dremel)and thin wheels.This bend is what anchors the system from turning,even though the shank is epoxied in the handle.
We still do a tremendous amt of handwork....rasp,file,...and socket caps are everywhere from reloading to shop fixturing.Not for everybody.... but considering some folks have spent careers at fitting benches... well,they bring a touch more respect to the craft.The figured BW (black walnut) is my fav.Quick wipe with mineral oil for a finish.Enjoy,BWS
