Want to Buy Koraat near wedge (maybe 1/4 hollow)

I'm looking for a Koraat near wedge (maybe 1/4 hollow). I will eventually get one directly from him but am curious how my face will react to the harder steel. I'm used to vintage Sheffields and am curious if there is a difference. If I can get a deal on one used, I would appreciate it.

Thanks!

Definitely a big difference. His steel is like 65hrc versus 55+/- for Sheffield.

Can you feel that on you face? Is it harsher?
