HISTORY: Elof Granberg introduced this as the FIRST hand held 12 volt sharpener to the chainsaw accessory market in the 70’s.

    I have 3 chainsaws and 5 wooded acres of property. I tried hand filing and never was able to do a satisfactory job on my chains. Before I bought my Granberg, I used to wait until my chains were starting to dull and take them in for sharpening. I finally bought the Granberg and I actually kind of look foreword to sharpening chains myself. There’s a slight learning curve but very quickly you’ll be having razor sharp chains every time you cut!!! Just know what the pitch of your chain(s) are and use the correct grinding stones.

    I can’t praise this little guy enough nor the company behind it. This sharpener makes sharpening a blade evenly a breeze. It is like having a workbench sharpener out in the woods. I run mine off a Milwaukee 12v battery pack so I can get a ways back and not have to run to the truck to sharpen my chain every time. The company sent me new parts no questions when I had a bent shaft. Love this tool and this company.

    This is by far the most precise sharpener out there for the price. it does a great job. Take a few minutes to understand the set up and you will be glad you purchased one.

    After 5 minutes of use the motor assembly developed a clunking noise from within…like something had come loose. I sent complaints to Granberg’s CS department but received no reply. After a couple of attempts I finally received a response from the seller, Forestry Suppliers who offered to help me deal with getting either a refund or warranty repair from Granberg. My low rating applies to Granberg and their product and not to the seller, who has been the only bright spot in this whole process.

    Awesome tool – it took me a few tries to get it and myself dialed in, but I feel like I’m getting my chain factory sharp again, for the first time ever. I’d had my local Stihl service shop sharpen my chain a couple of times, but I can now get a better result myself. Using the tool for setting raker depth works really well too, no depth guage required, no guesswork around adjusting raker depth to suit a particular wood.

    The Granberg 12v G1012XT chain sharpener is the best sharpener I have ever used. I cut a ton of firewood every year and run a coupla chainsaw mills too. The fastest easiest way to keep your chains sharp hands down!!
