This is the first time I've posted in the "Throwers" forum ---------- I'd just like to say that I got "good" at throwing bladed weapons/tools by useing a sheet of newspaper -- there has to be a bit of a wind , but I'd release the sheet of paper and try to nail it while blowing across the ground. The thing I liked about this was you almost always had a differant distance and you had to learn to adjust for it.
I am in the "1/2 & 1/2 camp" on throwing your only weapon if in a fight -- funny thing about fights is that there are almost never two that start/end the same way. It is good to see a adult conversation on throwing without the Rambo BS that it tends to raise.
I just got a 2"x72" grinder and think I'll try my hand at makeing a few throwing knifes --- I'll have to do a little research on blade steel etc. but I am pumped to try grinding a few out.
Stay safe -- Bird
From what I have read, 1075 or 1084 would be the best as they have the easiest heat treatment for low cost high carbon steels. An oil quench is recommended for them. 1055 is used for axes so it should make durable thrower but it could be tough finding it in the thickness and width that you want.
You could grind a knife out of a file or rasp and then temper it back to gain toughness assuming it isn't case hardened.
