So you got me wondering. I just went through 6 tool boxes (various purposes) and came up with five 12", three 10", four 8", three 6", one 4", and out in the shed, I have one 16" or 18"?. I know that I must have at least 4 or 6 others in various tool boxes vehicle trunks probably 8".
Thats after 65+ years of collecting. Some were my dads, some my grandpa's, but most were from field work jobs where I was totally without tools and ended up buying stuff at the closest tool store. Most of mine are Crescent, but a couple of the 6"ers are Sears all older models made in the USA except one Sears Japanese, which I can't tell from the USA. They all have had a LOT of use some in horrible environments some only in lab or workshop clean environments.
Somehow, early in my youth (in my 30's?) I figured out which direction to use one. Never broke one but dropped a 12"er about 40 feet to a
hardrock surface and little damage.No heads were damaged. I've seen people break them, but either they were a h--- of a lot stronger than me or their choice of tools was from HF e.g. (i.e.?, I never can decide which of those to use) made in China.
