I wanted to try this blade as 4 tpi blades leave a rough cut. I sawed many logs into circles 7" to 12" in diameter. I've found that the wider the blade used, the smoother and straighter the log goes through. several 2 year old oak logs, 10 inches in diameter. the blade ran smoothly. No Smoking. not hard to press. I immediately ordered two more of these knives. the price is great. priced at $12.99.
