    How often do you sharpen your planer knives?

    Was doing a lot of thicknessing today and my planer was not feeding the stock very well... I was having to push/pull it through with fairly large force. I thought the rollers were screwed up, but it finally dawned on me that maybe the blades were dull. The surface texture was still nice and smooth though, so I wasn't sure. I finally took off the guard and sure enough, there was a noticeable dull edge on the blades, although they still 'felt' sharp.

    They were reversible, so I flipped them over (first time I've ever done that). Wow, what a difference - planer is about half as loud and feeds stock nice again (I also cleaned the rollers with mineral spirits at the same time).

    So I'm curious - how often do you sharpen/change your blades? And do you tend to sharpen, or replace?

    I have a Ridgid planer so the blades apparently can't be sharpened but are reversible.

    I think I've had mine for 10 years now and I'm on my 4th edge so about every 2.5 years. Usually I can feel the finish isn't as smooth but the signal to me is when the planer sounds more like it's beating the wood rather than planing it.
