They should have been good out of the pack. If not, send them back to Magnus they will sharpen them and send 'em back. I have had them resharpen mine after using them, no charge.

I think Magnus is a good ol' American Company doing business like it should be.

I use the 2 blade stingers and after all the practice and killing 6 deer, they still shave the hairs on my arm! Good company, great product!

A wouldn't sharpen them until after I shot animal with them . Because they are SHARP right out of he box .

I use about 3 different grade of stones, coarse to fine. At this point you could probably skip the coarse stone. Take the insert out. Lay them on the bevel and push them away from you. Make sure you're riding the bevel. You can feel it. do some licks on both asides and flip it over. After I'm done with the finest stone, I'll strop them on cardboard and finally a leather belt. There is no such thing as a broadhead being too sharp.

Ive got a 5 stone Lansky system and I take the blade off of the head and clamp it in the Lansky and sharpen with 17* with medium, fine, very fine, could shave a gnats @$$ after it was done.
