I have purchased several of these Olson saw blades in the past and have been mostly happy with them. This one was really just "boring". I've ordered a new one hoping it's comparable to those I've bought in the past. but if it's like the last I will not come back. TO UPDATE. I ordered a new blade, but then I noticed that the delivery time is about 10 days. I canceled the order and will find something else to work with. Who uses camels more for delivery?
