Trying to get some base data to do testing. I am using a basic digital postage scale. I added cutting board and item to cut, then zeroed. To slice an onion in half, I saw max weight of 6 pounds. Does this sound reasonable? Is this pressure or force?
once i have some base line numbers, I want to apply the same weight using different cutting boards and see if board material effects sharpness. Test would be edge against board with chosen weight, move blade back and forth several inches ?? times. The test is to see if there is measurable difference in sharpness after cutting on PP, HDPE, face grain wood, edge grain wood, and edge grain wood. Blade would be mounted in a vise and moved on a linear rail so you would be looking at a 'pure'(no side forces) pull cut.
sound like a reasonable test or am i chasing unicorns?
