These little beauties are smooth operators which waste no time in getting chains restored to their former glory - or at least pretty near the standard they were at before become dulled by use.
Most of these sharpening devices are electric-powered and attach to a bench top in your workshop but there are a few exceptions - the superb manual Timberline sharpener, for example, fixes directly onto a chainsaw's bar and does an incredible job on any type of chain.
This innovative bit of gear has a hefty price tag of around £180 but this is the sharpening tool of choice for many pro chainsaw operators. It's capable of sharpening each tooth on a chain to the same length and angle in just a few seconds.
An obvious benefit of this device is that it can be taken out with you if you are working away from home. It works with a high-grade tungsten carbide cutter which is turned with an attached handle. It is capable of shaving a thin slither of metal off each tooth, meaning a chain will last even longer than normal.
The Timberline sharpener really takes some beating and many happy buyers have reported that it can get old chains cutting like new after it does its thing!
