There are a few reasons that a skelly handle is better for some knives than res c. 1 it is a EDC and can be easily carried and concealed.
2 it is a thrower ,most handles break but res c bounces and throws the weight off.
3 a very long knife needing a 2 hander handle looks silly with res c.

Now #1 is probably better served by INFI or 52100.
#2 would have me totally ,I have a CarbonV cord wrapped thrower I love.
#3 would be even better a S7 AK4S7 would be awesome especially in a CG version for around 200$. It would change the world of martial arts and self defence swords(admittedly a very small world populated with a fair number of whack jobs myself included)forever.
