Hi grumpy, the bedknife buddy contains a fairly fine file blade that is reversible. Replacements can be bought from any good tool shop. The instructions for use do not mention putting oil on it during use. Naturally, one should clean all filings away after sharpening.
Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member. Kindest Regards, Darryl
