I was searching for a long while and finding frustration. I was fortunate to find Black Forest Wood Company and confirmed on line and by phone that they had the Burrs I was seeking. My phone help was superb... like talking to a nice neighbour. Additional follow up was needed for my order and the patient crew handled the order without hesitation. I am sincerely grateful for their time and efforts... AND I am more than willing to pay for the burrs from a Canadian Supplier... even though they are American, I still want to give the end business to a Canadian. As for the Burrs.. I have been using Kutzall Burrs for over 20 years and have heavily used them on hard, dirty and oddly grained wood with consistent results and have adapted techniques of securing and holding my pieces to compliment the burr profiles along with the pull force from the grinding and safety to enable no impacts to eyes, lungs, ears, fingers. If I could improve Kutzall, I would make the shafts longer (100 to 150mm) using strong rigid steel and tapering the steel shaft at the neck of the burr to enable clearance for deep cuts and tight situations and visual site lines for the carver. Watching the Kutzall videos online.. I must say, they need to enforce and self assess much stronger health and safety for their demo users... safety glasses, gloves, face shields, masks for dust, hold down systems made and tested like mine that they can show..., I rarely see any of this.. My biggest concern from is their use of a leaf blower to clean dust off of a person.. especially the face "eye impacts" even more so with toxic exotic woods. This blower mistake has been observed several times. They should also mention having and emergency eye wash system at hand at their demos and advertising... I have one in my shop, its only natural and smart. Smiles and Thanks Francesco
