Had a buddy the next town over score a pile of logs behind a new garage going up behind his next door neighbor. Lots of hard maple up to 30" diameter and straight as one could dream, plus several big locust logs in the 26-28" range. Borrowed another buddy's 36" Husky since my little 18" Stihl was going to be overwhelmed, and went to town on the maples. Did 8-9 cuts, then attacked a big locust on the top of the pile- big mistake. Did one cut and started another when I realized that the saw teeth on this new blade were dull as a butter knife. The wood may be a wonderful burn, but others on the site who have mentioned that locust goes through chains were 100% correct. My first experience with locust in 30 years of burning was an eye opener.
