Having had a good look round Hydra we decided that the spike wasn’t working particularly well because it didn’t have the reach it needed to have a serious impact on abything (most hits were with the arm rather than the axe head).
We decided to go for a new longer hammer rather than a spike. It’s made from tool steel and it’s just going off for a nitride coating so it’ll be fun to see the results (unless you’re the one getting hit!)
