I am continuing to use it several times since I encountered this product. I am using it for rework after grooving / large cutter etc etc. I'd like a series with a slightly lower price from simple packaging.
Smooth slitting. Sustainability of sharpness also responds more than price. Therefore, I think that it is easy to use without irregular vibration etc. What's worrisome is the extent to which the sound when cutting is disconcerting. (that's all)
It is used for the first time today after purchase. I replaced it because the previous blade can not be cut, but I was surprised at the same sharpness as the blade I used before without cutting at all! It is! It is! It can not cut at all. It is normal to sell such products for about a day (home center). It was an item that I could not use at all for professional use. Let's buy and buy. It was extremely shocking.
