SHARPENING SPEAR TIPS

Thread Status: Hello , There was no answer in this thread for more than 90 days.
It can take a long time to get an up-to-date response or contact with relevant users.
Yup, get yourself a better used bench grinder. You have yourself a new, sharp tip in seconds!
I would go with the file. Low tech and portable. The grinder may mess up the metal's anti-rust protection if it is heated too much. Of course, it takes some practice to get it right.

Fair enough, it is portable and a super solution for on-the-go fixes, but it is much much harder to file it down to be super sharp by hand.
 
More important than rust protection is temper. The points ability to hold an edge. Overheating while grinding can anneal the steel (break temper). This means you will actually need to sharpen more often. You want tempered steel to hold an edge.

Better than a bench grinder, is a low speed grinder, mine is made by Delta Tools with a flat wheel, and a vertical grinding wheel. The low motor speed prevents heat build up. With low speed you can quench with water without breaking temper.
