For some reason I can never get 4/8 blades as sharp as my other straights.

When I'm finished with the others I can run the blade down the hair on my leg and it just pops off. When I do it with any of my 4/8's (and I'm the only one who has honed them) it doesn't do that.

Most of them are Spike from Oneida Cutlery from Ebay. I had some other brands though and I have the same problem.

I spent a lot of time the other night honing one just to see if I could get it sharp. Nope.

Any idea why I only have a problem with this sized blade?
