I bought a 5 piece Old Hickory kitchen cutlery set and I'm disappointed with the factory edge.They are made out of fully heat treated and tempered 1095 high carbob steel and my question is: If I sharpen them on a spyderco sharmaker,how long will it take me to get the sharp enough to do all kitchen chores while holding the edge for a resonable amount of time? and would you guys recomed the 30 or 40 degree angle?
