Just want to say.,if you feel you need to sharpen in the field .I would if needed.Better than being dull and making the job harder than it is.Since we are talking knives in this topic.Anybody seen or has one of these.Got it through a hand me down type deal.Western w36 or something like that ,think they where pretty common a few years back.
