Where ski edges terminate

Been wondering about this for a while and couldn't find a thread.
Skied a pair of CT 2.0s for a season of park at copper mnt but this led to a blown out edge.




The first image is the tip and you can see the edge is completely missing and the next is the tail where you can see the failure starting to occur. These failures occurred where the edge was already split or broken from the factory. There are four of these splits on the ski. Two on either side of the tip and the tail
an example on a pair of armadas. Why is this so? Does anyone know? Now check out my current planks.

These are line twp and have a continuous edge in the tip and only one split at the very tip of the tail. This seems way more durable to me and it's partly why I bought the skis. Watch out for this in skis guys. Let me know if you know why but I think this is probably just done because its an easier and cheaper way to factory produce skis

Shove some glue or epoxy where the edge used to be and you'll be fine. Tools not jewels.

Right, and I have multiple times. Jb weld is the only thing holding them together at this point. Besides they were covered under warranty but that's not the point of this thread. I want to know if anyone out there knows about the ways edges are cut and installed and why. I'm not concerned about my particular skis but I think others should be away of edge design when thinking about new $700 skis.

In theory, a 4-piece edge is to allow additional movement in the tip so that vibration from landing and such dissipates more easily than on a single piece or two piece edge. Idea being that the ski itself is allow to flex more as a unit, lessening the stress on the material bonds in the tip. Same idea on skis that are running no edge throughout the tip.

I suppose if you were running a tip shape that was literally a single radius arc might make production easier to go with a 4 piece edge but....no one who actually cares about designing skis is doing that.

Obviously this varies in practice though as there are a lot more factors in play than just the a 1 or 2 or 4 or 3/4 edge wrap.

iggyskier3/4 edge wrap.


Hey Iggy I wrote you a haiku

Three quarter edge wrap
Is how I like to build skis
It is the best way
