Problems with traditional shaped harmonicas

This maybe a total n00b question, but I cannot find any answers on the web.

My first harp was a Honer Special 20, and it rubbed the little skin web area between my thumb and forefinger raw. The comb has a bit of an edge and I attributed it to that and bought a Suzuki Bluesmaster (rounded case). Problem solved and I like the Suzuki sound better. But being new, I decided to try out various harps until I had an idea what the differences were.

So my latest purchase is a Lee Oskar, again with the boxcar design. I love the sound of it, but it is rubbing the hell out of the skin between my thumb and forefinger, similar to the Special 20.

I hate to give up on the Lee Oskar because it sounds great. So what am I doing wrong that the standard shape harmonicas are beating up my fingers? ???

Thanks

Get an emery board and file the edges off on the ends of the plastic comb. Makes a world of difference.

And then smooth it down with a finer grit sandpaper.

It sounds to me like you are gripping the harp too tight.
