Recommendation for metal brush cutting blade for Stihl FS? Thread starter Nonprophet Start date Mar 4, Mar 4, Nonprophet ArboristSite Operative. Joined Jul 31, Messages Location Orygun. Working with a Stihl FS with bike handles. Mostly cutting thick underbrush--blackberries, rosehips, etc.
I've seen the Stihl 3-bladed ones, reasonably-priced but they get mixed reviews on blackberries. So, I need something that going to cut blackberries, doesn't cost too much, will last for awhile, and is reasonably easy to sharpen I use the Windsor or Sandvik triangular blade. It holds up better than the Stihl blade and costs less than half.

We destroy at least a blade a week in rocks. In berries I use more of an up and down motion rather than sida to side. Make sure you have an extra rider cup and nut. Zombiechopper Addicted to ArboristSite. Joined May 11, Messages 3, Location Saskatchewan.
I have the three bladed stihl one that I have tried to use on my FS I don't really like it to tell ya the truth. It's good on heavy weeds like big thistles, but it sucks on woody material.
So, don't get that one! From what I've read if you have actual small woody stuff you want the circ saw type. I would suggest one with fewer teeth and no carbide.
You should be able to sharpen it yourself then. Last edited: Mar 4, Zombiechopper said:. Joined Nov 21, Messages 13, Location Michigan. Try to find an Oregon Shredder blade. Not so good on saplings bigger than 2" but for blackberry brambles and heavy woody weeds and grass, there is nothing that compares. They sharpen back up with a grinder, but it takes some serious contact with rocks to dull them.Pigroast uncertainty What are your thoughts? Started by Lorenzotto on Forestry and Logging.

When filed with this file it completely changes the profile of the tooth from that of a new tooth. I'm cutting 2" to 3" hawthorne and locust saplings, mostly. For the power available in this saw, it's just not cutting well at all, And, I think the problem is at the blade. You need to get the angle correct, it took me some looking and tryin but I got it.
Jasper How about some more info on the blade you are using. Not sure I understand the reference to a Japanese mfg. It is 7. Beenthere, I mention the Japanese blade because SwampDonkey had said that the Japanese blades were paraphrasing not very good in one of his older posts.
He uses Stihl's Swedish 9" blades. Per the part number, I am using the very same blade that you have shown in your post. It seemed to undercut the area just beneath the tooth. I'll try to post a photo soon. It's been a while and I'll have to get back up to speed. I may be back here seeking advice again. Thank you.Brush Cutting
Might as well start correcting the mis-filing that has been happening, so you get back to the good cut you mentioned the blade had when it was new.

Just as a general comment, once you get by the file size, angles etc for me at least where you sharpen makes a difference. Lots of folks sharpen over the knee and can do a great job.
