A real world test of the Silky Katanaboy 500 saw no speed cutting no ninja stuff just cutting trail and assessing the saws abilities , I still use my silky Bigboy 2000 XL all the time for smaller stuff, and it is capable of cutting all the trees i did today but I have to say the 500 made very light work of the bigger stuff which was very nice indeed.Glad I got one for sure, I picked it up at the Arborist supply company in Calgary out near Calaway park I was very impressed they had every Silky saw in stock I was like a kid in a candy store :-)
