I have a user plain edge Kershaw Blackout for sale. It was a sample model so it has "sample:not sharp" written on one side of the blade. I put an edge on it and used and carried it for about 6 months now and lockup is tight and the blade deploys quick. You could paint over the blade if you want but since it was a user and not that noticeable unless you know its there I dont worry about anymore. I accept postal MO only. Price is $20. Thanks.
