As expected it is OSG. Compared to inexpensive manufacturers sharpness does not fall. Although price difference is three times, life expectancy is likely to be three times.
As expected it is OSG only, it can be used even hard-to-cut materials. It may be cheaper finally than to purchase inexpensive goods of unknown maker, often with knives. Nonetheless, I'm really satisfied if I make efforts to lower the price a bit more.

Although the consumption of tools is not so much in many types of small quantity production, inventory has become less, so we ordered 3 manufacturers including OSG in terms of price to try in order to reference the next order. As expected or OSG, it is impossible to place orders in units of ten as usual, but I will continue to patronize it in the future.
