The carbon clusters are designed to cut through railway sleepers, sheet metal, tree roots and other timber in seconds. The technology originates from the Canadian logging industry. Cutting through tree roots with a chain saw blunts the chain as soon as it comes into contact with dirt so they needed something a little more rugged. Carbon clusters don’t have sharp edges in the way a blade does so you can happily hack out tree roots and fence posts without having to worry about re-sharpening.

The first thing I noticed when fitting this blade is that it doesn’t have a directional arrow on it. Either way will do to start with, you simply turn the blade around as it becomes blunt. This effectively self sharpens the blade by changing the direction of the cut. You continue doing this throughout the life of the blade. At first glance the clusters look random but if you look more carefully you will see that they are balanced around the blade. This is intended to reduce vibration but when you run it slowly there is a pronounced wobble on the machine. You can’t expect this blade to run as smoothly as a diamond blade but much like wheel wobble on a car it is worse at a certain speed. If you run the saw at top speed it gets smoother but never that smooth. The cut is also a lot more ragged than a sharp chain saw so you won’t be looking to use it on first fix site carpentry. If you are cutting out old joists, roof timers and other timber with nails then this is the blade to use because the odd nail doesn’t worry it at all.

Obviously with a name like 'Ripper Blade' it doesn’t take a giant leap of the imagination to realise what this can do in the wrong hands so be careful out there. The Ripper Blade retails at £126.65 and Diamond Blades claim it can tackle tree roots, small trees, railway sleepers, decking, wooden planks/boards, nails, screws, tar, flashing, thin sheet metal and plastics.
