I have gotten mine pretty sharp with the wheelie, which I love so much I just got two extras. However I am currently working one on my Lansky, which is similiar to Simmons "Steel Master", that I use free-hand. Hate to buy it if I can use what I have. I did get two of the Ceramic rods from Simmons. I picked-up a small three sided file, 1/4" or so. The "Tail" of the file must be small enough to slide into the angle holes on the Lansky jig. I wanted to change the angle to 25 degrees, which I like on my heads. The file works well, and is faster than the Lansky stone. The file is narrow enough that it will work the curved area fine, especially if you use angled strokes. When I got the angle set I used the ceramic rod. I like a smooth, mirror-like edge. It is a little too big to fit in the angle hole, so I used two plastic tie-wraps to attach it to one of the Lansky guide rods. Now I can work the bevel at the same angle I've set. I'm about finished with one and it's sharper than the wheelie gets it. It's shaving hair, and I'm not quite done with it. I have also noticed with other heads that if I set a 25 degree angle first, the wheelie puts a better edge on. It looks like the factory bevel on the Sharks is about 30 degrees, which I like on knives since it seems to be more durable, but I prefer a shallower angle on broadheads.
