I have been clearing Rhododendron Ponticum on the island of Arran in my retirement for some 14 years and have found the Silky Zubat to be an amazingly wonderful tool. When I started they were very tough and would never break and they stayed sharp for a long time. Prices have really gone up but I am sure that the quality has gone down. I have taken care to buy the expensive blade replacements but in the last 3 weeks I have had two blade breaks and that never used to happened years ago. Just got blades trapped a little bit in the cut but broke far too easily.Anyone else had the same problem? I am also sure they get duller quicker now. Are these all fake or has Zubat production deteriorated? Anyone know of a reputable dealer?
