To use it with a separately sold guide, there are only options for this item. I am satisfied with Saigaid and purchase this product whenever sharpness is bad. However, I do not know if I am using heavy saugides or not, but I feel that sharpness will be worse for a while. Satisfaction will go up if you last a long time.
Purchased as a spare blade replacement for "Saigaido saw set" previously purchased here. Sharpness is good and it is easy to use for DIY amateur like me, but there is no shop closest to us, and here was affordable at mail-order site. I want to repeat in the future.
