knife sharpening

How does obvious sharpening affect the value of a knife

[bayonetman]

Any obvious sharpening will lower the collector value of a knife. How much it lowers it depends on how much it is sharpened and how obvious it is.

 

If it significantly changes the contour of the blade, it will cut the value by a great deal, probably about 50% and most collectors will not want it at all.

 

If it simply removes finish or results in scratching or marring a bright blade, it will probably hurt it by 20% to 30% or so depending on how much finish is removed, maybe a little less if it is neatly done. Again, many collectors will lose interest if it is a common item as they can easily get a nicer one. If it is pretty uncommon, then there may still be a market but it will definitely lower the value.

 

I have a couple that are pretty roughly done, but I got them directly from the user along with the history of their use. I still would not and did not spend anywhere near as much as I would for a nice one.

thanks, I have seen some nice M3S AND 4S that are nice except a dip back by the riccasso that would indicate sharppenig and going for as much as others in much better condition and just wondered. Thanks Mike

Any used knife will exhibit some edge wear and possible sharpening. If the sharpening is done well and with a good stone, it decreases the value over an unsharpened or factory sharpened knife by a little; if done poorly or with a file or grinding wheel, the value decreases sharply. If someone has taken a wire wheel to the blade, the value can be 10% of the unsharpened knive. Rarety can trump condition sometimes, but for any knife, the more sharpening, the lower the value.
