I engave mytools, I use paint markers to put my initials on them for quick ID (craft department at wal mart) and mark my tools in several places. I still have bean stolen from a couple of times this year. The advantages of marking tools is that they are more difficult to sell at pawn shops and if you have an elert police officer he might spot your tools especially if they have a suspect. Marking tools helps in identifying them if they are recovered, I figure the people that make them put there name on them I should put my name on them so I know who owns them legally. Also if a friend borrows a tool you can make sure you get it back.
