Rex, I like the sawteeth on the 5!! Hope to have one soon with them on it, especially now that I have understood that this option is still available.
And here my only (at the moment) #5, with nickel silver hilt, custom supplied ironwood, finger grips and thong hole: it arrived from the States with the point damaged, so I asked to a talented italian knifemakers, Mr Roberto Bernini, to touch it up.
