The head has two different wedge tips, one for larger blocks and another with an acute bevel to split kindling. Green straight-grained blocks 8" or less in diameter can be split with a few blows; larger blocks require more, especially if the grain is interlocked.
Made largely from plated and epoxy-coated steel, the tool permanently installs in a length of log by drilling a single hole. Drill bit and assembly wrench included. Maximum length of block that can be split is about 21".
Designed in Sweden, this is a safe and easy way of preparing firewood.
