I believe in todays world and the emphasis on safety and liability, it is probably best, for the owners sake or contractor for that matter to get a sharpener. As you see the progression of safety records and how they can affect the ability to be considered for contract, it is smart to keep all lost times to as low as possible. Sharpening tungsten, although done for many years, with a grinder can, and has for me, caused a few skinned fingers and over the years a few eye mishaps. One piece in the eye or infected finger can lead to a lost time....sorry but, this is the grand scheme of things and what is coming
Return to tungsten sharpeners.
