Nothing wrong with an allen wrench. If you need more leverage, just slide a socket with extension over the end for a cheater bar. And all you guys cutting your fingers with knives need to up your game. I whacked a couple fingertips back in January with an electric wood planer. Those m'fers don't play. They eat flesh as efficiently as they do wood, maybe even more so. Luckily, fingertips grow back. The fingernail bed just keeps going and going. At first I thought I was gonna end up with a strong hand.
