The Obsidian-S is a work of art!
Beautiful as it is, it's rock-solid. I prefer the G10 scales of the -S. If you need to round the corners some with fine sandpaper, to tailor the fit & feel to your hand, nothing could be more simple. Just be sure to do so conservatively; you can't put back what's been removed... I opted for the Spear blade. It's shank-tastic! I love it! I assume the Bowie would flip a little more nimbly, especially for a beginner! But I didn't buy this to practice & play with...I have Maxace's practice models for that. In 2008 my balisong saved my life. In a heartbeat, do to equipment failure, I needed to cut/dig my way through a heavy rigging line, that was seconds away from dragging me to my death. A tipical folder's joint very likely would not have been strong enough to handle the abuse. But the balisong is far stronger. I will carry one for the rest of my life; and I'll probably be buried with it!
