Useful Gadgets

I bought this very useful little gadget online for splitting timber for kindling, it works great except for knots  but then nothing works with knots except for a saw. 

Interesting Can, but I think I'll pass.  I've never chopped wood in my life, not likely to now .  My most interesting/useful gadget indoors these days is the plastic claw thingy that releases the vacuum in jars so I can open them with arthritic hands.  Sad, isn't it
