Did not like blood trails/results from the previous version of the Sevr...was called the Ulmer Edge the first time around. 1.5" two blade that was very accurate. Did arrow a grizzly, Roosevelt elk, Blacktail buck, Coues buck and a black bear with them but haven't used them since 2015. I've had much better results/blade trails with 3-blade expandable since that time.
They were introduced in 2018.
