I wrote Amazon a long letter on this one.......when I returned item. Their presentation of this blade on their site is terrible and leads to a mis-order!!!!. And if you need the one that fits the Lithium Rapala knife rather then the ni-cad powered one, there is an added hole for the Lithium, you stand a high chance of getting the wrong knife on their site!!. . And as you check boxes making selections for type & size, the change in the photo is so suttle you don't even notice ..........THAT YOU ARE NOW GETTING THE WRONG KNIFE BLADE !!! AND IT ISN'T GOING TO FIT!!! It says their blades fit both knives , this is a lie. In defense of Amazon they were very nice on the return , reversing charges, and even letting me keep the item, which really of no use to me.
