Topic tags/keywords: forrest saw blade sharpening

I got my Forrest WWII just over 2 years ago and it cut like a dream. I used it for about 90-95% of all my cuts in my shop. For the past 4 months, I noticed that it’s a lot harder to push wood through the blade, especially anything over 3/4”, plus a decent amount of saw marks and burning. I clean the blade every 2-3 months I would say. I suspect that I might need to send it in to Forrest for sharpening. I was wondering if this was normal for everyone else to send their WWII for sharpening about every 2 years. Thanks!

As a side note, I got a Freud thin kerf ripping blade for stock over 3/4” thick, and a Freud thin kerf crosscut blade for crosscuts and they both perform exceptionally. They are highly recommended.

40 hours on a blade

its done and needs a grind

you might squeeze 80 hours out one and I bet some squeeze a lifetim

but 40 hours

and it starts to under perform and downhill from there

I would suspect that that is the main problem with the sawblade…you don’t clean it near enough. I have 3 WWIIs, and I clean my about every week or so, depending on how much lumber I cut…. 2-3 months is too long to go between cleanings…you will have a pitch build-up deluxe, and that’s what’s causing you to get burns and saw marks….. I have mine for a bout 2 years also, and have never sent it back to Forrest for sharping, yet….But it’s due. Clean the blades more often and see if that will help…Keeping the blade clean will make it stay sharper longer….

saw blades on a shelf, will stay sharp infinitly if left in thier protective rubber coating

if left unprotected….........................they burn….................wood

contrary to popular opinion, abrasion far less affects the longevity of a saw blade

corrosion is the killer

What you describe is an indicator that it needs sharpening.

I’ve had my Forrest WW2 blade for over 10yrs-it’s been sharpened 3 times. My experience has been that when it becomes hard to push wood through the blade it’s ready for sharpening. I’ve sent mine back to Forrest-they always include a $5 off coupon to help you save money.
You won’t believe how much better it cuts when you get it back.

If you have a loupe or 60x magnifying glass and look at the teeth, and see any pitting or flattened edges on the cutting edge, it needs sharpening

Send it in and get it sharpened. Buy a Freud P410 as a back up. You may never go back to the WWII. Its an awesome blade
