I don't like measure tapes and prefer solid plastic or metal rulers. Also, I love practical and "in theme" gadgets. I've decided to make a ruler for French-Indian War games - the motive of choice was tomahawk! Laser cut in plywood (it's better than MDF, because it has wooden facture), scaled in inches. I've made few prototypes and after some minor changes I'm quite happy with the results. Now it looks like that:
I'm going to make some for our bunch of players anyway, but I'd like to know if anyone would be interested to buy one. Price is 5 euros apiece.
