Well, finally tried my new lazer yesterday with the "china" blades and all". It cut really well with less then effort then my 15 year old mora. So far, I am very happy with it and if the sweden blades are that much better then I will be extremely happy. Yesterday we were cutting thru 10-12 inches of ice in 10-20 seconds. I can live with that! I still say though that my old Mora with new blades is not much slower, but needs a hell of a lot more pressure.
Also the blades did not slip and bit really well when starting a hole. At times breaking thru the hole it caught a little bit, but not a big problem at all. When nearing the end I just eased up on the pressure and she broke thru every time.
