The picture above shows the normal replacement blades, which I've purchased in the past an which worked very well. The ones I tried this time taper to a point and are serrated up to the tip. I've used both pairs if new style and they don't cut well, like they are dull. However, they agreed brand new. I will go back to the original style with angled, non-serrated tips.
Purchased these blades hoping they would be sharper and cut better than the regular Mr Twister blade. Very disappointed in how much pressure I have to apply just to get blade thru a crappie. Would not recommend.
