Spleify-A 2 sided Smith's with fine and coarse at Gander-about $20. A fine and coarse credit card size and thinness at Woodcrafter's (great for wallet carry) I think these were about $12 each. I'd never used diamond hones until I bought these and have found them to be real good for novice sharpeners like myself. I also have the Lansky system at my house for more detail sharpening.
