Quality looks good but diameter is too small for my 8oz hammer head. I wish they would post the measurements but I'll probably keep them in case I get to use them with another hammer/tool in the future. I don't want to cut it short using the thicker part of the handle instead of the 8oz head, so I'll have to order another brand or just go to the local market. I know hammer heads vary a lot, but you might think they're on the wrong side of too much material (which can always be removed) and too little material (making the handle useless for my application). Still 3 stars because the quality of the wood and the grain are excellent, so I can't dispute the quality.
