Faithfull Electric Chainsaw Sharpener - 85W / 250V – Efficient & Easy Chain Sharpening for Electric & Petrol Chainsaws

Having owned this now for around a year and used it to sharpen around 20 chains, I wanted to update this review. I’ve upgraded it to 5 stars from 4 as I originally didn’t like the clamp. But having now used it many times I realised that I was using he clamp wrong, there is no need to clamp the chain for each cut, simply adjust it so the chain slides through it and use the backstop to keep the tooth in the right place. Anyway it has saved me loads of money on professional sharpening or new chains so I think it’s really good value. I suspect I'm like many DIY wood-choppers and I'd ended up with quite a collection of serviceable but blunt saw-chains. I'd originally bought myself the round file sharpening kit but it was a ball-ache and so once I'd had enough of sharpening I'd just buy another (hence the collection). I decided that I was going to get my chains professionally done and phoned a local company, they quoted £15 each if they were off the saw and £20 if they were still on, that was when I decided to take the plunge and buy one of these and I love it. It take around 3 minutes to set up (I screw mine to a tree round to hold it steady as I don't have a work bench). Set the back stop, set the grinding depth and then you're away. Takes a couple of mins per chain and they are super sharp once done. Don't bother with the instruction manual just watch the video. Only downsides, the clamp is a bit of a faff, I've seen there are versions where the clamp is released with a handle, that might have been better and the end stop is a bit slack. That said for the price I'm not complaining. It's a great tool for anyone who is an occasional chainsaw user

Having spent over 20 years of sharpening chainsaws with a round file was looking for a quicker way to do the job.... (And I had also lost the wooden handle from the file!) This appeared to be the best combination of build quality, price, and availibility of original grinding wheels at a reasonable price. On unpacking - it is a bit 'plasticy' and is definitely aimed towards the hobyist rather than the professional. The mouldings on the plastic needed a little 'modification' to take the sharpness away and to make the depth stop sit accurately, not on a little moving seam of plastic. This is the reason I have given a 4 star rating. Setting this up is dead simple; the most awkward part is bolting it to the bench!!! (Tip - mount it further forward than you think, to allow the chain to pass freely between the edge of the bench and the overhang of the chain guide when turned round BOTH ways!) Once you have set the angle at which your chain should be sharpened, you can easily see and test by eye (with it turned off) where the grinding wheel will touch the chain and small adjustments (forwards/backwards) can be made so that you can skim the smallest edge off the tooth and adjust the depth of 'grind' so it just glaces the base of the tooth. In all honesty I had this out of the box, set-up, tested and 2 chains sharpened in less time than it would take me to either find the file or sharpen one chain on the saw. Yes it takes a little more material off the chain than filing; but when you consider that chains do not cost the earth and by sharpening with this so that each tooth consistently ends up the same length, same angle and same depth of grind is a good trade off. The result I feel cuts better, straighter and stays sharper a little longer. In short a great tool that does the job intended, but like many mass produced items from China could benefit from better finishing and quality control.

After spending the last year trying to use round files that go blunt quickly, teeth are sharpened unevenly and they don't really help when you hit nails!. Its a delight to use this cutting stone because it actually creates a super sharp chain. As said, after hitting nails, the cutting stone can take off a lot of metal a single pass. Can't recommend it enough. It is made well. I did have to adjust the chain saw clamp because it was too tight, but this was easy to do. You should attach it to a workbench (bolts not included), I can see using this without bolting down would be dangerous and hard to achieve an accurate cut across all teeth.

I've been sharpening my chains with a hand file for years now; its a chore, it takes ages and it gets them just barely sharp enough to do the job properly. This thing on the other hand is brilliant! Its a pleasure to use and gets the chain razor sharp in under 5 minutes! I really wish I had brought this years ago. Not only is the chain razor sharp, it gets every tooth cut to the same specification so you end up with a much cleaner, straighter and easier cut through the wood. The instructions are fine, but its that easy to use you don't really need them. Just mark your first tooth with a marker pen, set it to 30degrees left, whilst the motor is off line up the chain with the adjuster, then engage the lock, turn on the motor and sharpen each tooth until your back at the pen mark. Adjust to 30degrees right and repeat for the teeth facing the other way. Most chains will be 30degrees but check with your specification. One thing that the instructions don't mention is that if your chain doesn't fit into the guide rail gap, you can loosen it by pulling the locking level towards you and turning. Yes some of the plastic moulding is a bit rough around the edges (lets face it everything is made cheap thesedays), but the overall build quality is pretty decent - this is a heavy sturdy tool. I've done 3 chains with it now and the sanding disc is showing no signs of wear. Probably best to use this outside as it does stink a bit as the chain residue gets burned off. I would really recommend this, it makes cutting logs so much easier and quicker. And if you accidentally dull your blade on a bit of dirt, just stick it back in this for 5 minutes and you have yourself a brand new blade!
