No Ray, not offended. This was a valid line of questioning that has been voiced several times, and something each maker must answer for themselves. I approach it as a gift for the soldiers, a thank you...

Oh yeah, as a weapon, the ulu fits nicely for those trained in the reverse grip, or in the Nepalese Katar. A punch with an ulu concentrates all of the mass and power of the back, shoulder, and arm directly in line with the thin edge... easily shearing through flesh and bone. Even with the little ones I make, I cut patties from deep frozen sausage rolls with ease.
