Rob, I'd be interested to hear :D how you sharpen these heads.. Thanks for your time !
as showed to me by master blade sharpening guru, sensei ron @ kme ...
1. the blades must be straight and sometimes with new woodsmans there's a bit of concave showing. there are 2 basic ways to remove the concave ...
[list=A]
- use a sanding belt (table belt sanding station or a handheld belt sander that's clamped to a table top) with 120 grit or so and lay down the head so that the belt is moving from the back of the head to the point ...
... put a bit of added pressure on the tip to remove that needle point - it can be a subtle set of angles to each blade side or it can be a very chiselled pyramid look. i opt for the subtle angle (which is hard to see in the pix) 'cause i think that works best with bows 55# and under ...
- OR, you can hog the blades flat on a good mill bastard file such as a 12" grobet (also making sure to remove the needle point!) - just lay the head down flat on the file and push from the file's tip to its handle base end ...
2. after getting the blade edges straight, work the blades using that good mill bastard file ... that is, press and push the broadhead from the front of the file to the files base end. i do 5 pushes on each duo of blades, then 4, then 3, then 2, then 1. this will significantly raise a burr on the edges that can readily be felt. this head is now sharp enough to efficiently and humanely kill deer and hogs if well placed. but we can do lots better ...
3. remove the burr on the blades ... basically, this is blade stropping and can be done with a fine stone, or hard leather - i like a fine stone. the blade is
LIGHTLY pushed on the oiled stone, just a few strokes on each pair of blades.
VERY LIGHTLY. all yer doing is removing the burr which will reveal the razor's edge that's underneath ...
4. i like to do a bit of "final stropping", as ron showed me - just a few really
LIGHT strokes on a piece of corrugated cardboard ...
