Sister and her husband have an Escape Room business and added axe throwing last year. Not hard once you get the hang of it. Even my wife was sticking them.
I still have my old azz H&B Forge hawk I bought in ‘73. Also have a Joe de la Ronde forged French style hawk Ive had at least 35 years. Heck Ol’ Joe was at the Rocky Mtn National Rendezvous last July!
All you need to do is have a consistent release, same spot, same effort, from same spot on the handle. Be consistent. Then just look at what your tomahawk is doing, in regards to rotation. If your over rotating, the top of the head is hitting or the back of it move up a step or half step. If it's under rotating take a step back. Super easy man. You don't need to filing it with killing force, the weight of the head alone should stick it.
If I remember correctly you posted awhile back asking for recommendations on tomahawks to buy for this very purpose. What did you end up buying?
FWIW I make throwing tomahawks out of railroad spikes in a francisca pattern that aren't much as far as a real tool, but just for playing around throwing them it's damn hard not to make them stick.
Wife & I went to a local knifemakers shop a while back, he's also in to making throwing Tomahawks. He told us to give it a try, wife hit bullseye on first throw....and stuck it close on each try after. He thought he had a sale for sure.
When I was 19, my college roommate and I got into throwing knives and axes. We got pretty good at it. Haven't thrown one in almost 40 years, but I think it's like riding a bicycle, you never forget.
One night back in the reenactors camp during the shoot of "The Patriot" , production told us all to be up at the big mess Tent at like 8:00 to watch out takes from the shoot so far. Our little group was all setting up left front by the exit. About 5 minutes after they started film a straggler came in and sat down with us. Last scene they showed us was the big ambush where Martin( Mel Gibson) throws and sticks his hawk in the forehead of the one lobsterback. My goofy little pard with me says out loud, "Damn!!!!!! I’m glad he’s on our side!!!" Guffaws followed.
The late straggler who walked in and set right in front of us turns around, looks at us laughing, and hurried back out the exit!!! It was Mel! LOL.
Get a box of tennis balls, baseballs, something like that. Take about 3-4 steps from the target and start throwing those at the target. When you start hitting it so often it is boring, pick up your tomahawk.
Whole family used to throw when I had a hawk board in the front yard! Wife and kids! Kept the stupider neighbors away too! The cool neighbors would come throw with us!
