That’s a great question! Actually, it is THE question. You know how I keep referring to “sharp” vs. sharp chains? Another discussion about “trained” vs. trained would follow suit. However, that is not a discussion I can participate in for now.
Thanks again to all who have responded.
Here's a little bit of the "why" so many of you have asked about.
As a "Volunteer Active in Disaster Relief (V.O.A.D.)" member, we mobilize volunteers to cut downed trees up and carry them to the curb for pickup. Our target demographic for those we serve...
I didn’t want to limit the responses as there are numerous approaches to keeping saws and cutters productive. This is why there is only a single question, and the "other" option for more approaches that those that are listed.
How else would you ask how people keep sharp saws on the site...
This is a big part of the question. For smaller bars it takes less time to touch the chain up than it does to change it out. Of course if you hit something significant that takes more than 5-7 strokes per tooth, then you may save time by switching to another loop. On larger bars with full comp...
My goal is to gather data from the industry (you guys) as to how you get sharp chains on the site. I've heard of extremes varying from those who use cheap Chinese chains that are thrown away when they stop cutting to companies who have duplicate saws on the truck and just switch saws if they hit...
Do you think OSHA will make the determination of who is legally responsible? They both “should” have known better as ANSI makes reference to green log chart knowledge for the climber while the crane operator’s certification requires him to know how to minimize the movement of what he is rigging...
We have about 30 of those that were donated over the last two years. They cut well, but are not durable at all since they are made mostly of cheap plastic.
I like them for inexperienced cutters: There’s no clutch to burn out when holding the throttle wide open with the chain brake on. They are...
Dynaglide.
I know a lot of guys that like Zing-it. It is strong, but tangles more easily than anything I’ve encountered after getting a little age on it.
We ordered a spool of Notch Acculine to equip some of our Disaster Response Vehicles, but the jury is still out on its overall performance...
Great small saw! Professional construction, incredible power to weight ratio. However, Stihl has stopped production for the US.
We bought sixty of them over the last couple of years, but really had to search for the last 20.
The word is they are not going to replace it with anything...
For the record, TreeFan is correct. With the Conservation of Energy the calculation really is that simple.
There is a factor we have neglected: the size (distribution of mass). So far the log has been treated like a point mass that is dropped straight down. However, we are felling cylinders...
The rails bend over time and the depth gauges get a bit lower than they should. It’s a great tool for every third or fourth sharpening, but its freedom of movement still requires a disciplined hand for consistency. As with any approach, you’ll likely need to hit each tooth with the same number...
I'm not as familiar with the WC. Does it have a direct detent valve? It doesn't take much to clog up one of those.
Bandit uses a positioning switch that can go out as well. It's a cylindrical looking metal piece typically held on with two 6mm hex bolts. It will be directly linked to the handle...
I put some of these

on some Bashlin spurs a while back and couldn't be happier for an all day combo.
However, if I'm on the crane all day it's Kleins with steel insert Cpads. Heavy, but very comfy for me.
Yes, fully programmable. Raise or lower both cut-in and back-off RPMs. I believe there's a timing feature as well. However, I've never needed to adjust anything.
