Yes they do come your choice. The length of the tool head is about 1-3/4" and a working surface of about 1-5/8". This is a super easy tool to get used to for sure. Got it on Lennon's bench, Jello's bench as well as Revere glass and a set being handed to Eush today in Berkley just to name a few people that you can get tool reviews from. Super happy with this tool design.
