I believe that Badaxe tools requests a measurement of your hand when you order your saw. They make them in three sizes.
I’m sure if you talk with them they will be able to fit your needs.
They are expensive but very high quality saws.
Bad axe’s owner Mark Harrell’s wife died this week, so be understanding for a while while he and his two teenage kids take some time to heal.
He says he is still taking orders, but the pace will be reduced for a while.
