@globalmuseum That is wicked cool! Wondering what was on the other end of the Lewis tool?

@globalmuseum Would be much more interesting and educational if an actual video of it being used was shown instead of an animated depiction.

@globalmuseum seems like cutting the upside-down cone-shaped hole would be the real problem here.

@Twotired @globalmuseum yes.

@globalmuseum interestingly, I’ve always heard it called a Master’s Key, one of the secrets of a master stone mason. Known since ancient times. Also works okay with shear-legs (two long poles bound at the top and surmounted with a rope. Of course, it also required a hundred or so men to pull the rope.)
