Special Cases: Splitboard inside edges
Special Cases: Tip and Tail Full Wrap
When considering light impacts the edge (wrap) sort of helps. The edges can deflect small impacts and damage from lightweight hits (things like bushes and small trees less than 2 cm thick or so…) and provide a bit of protection from shaving due to edge scraping while skinning on splits or stomping on your tips and tails in the liftlines and stuff or while skiing. On the other hand, the damage caused by the edges up there on the topsheets probably comes out at six of one, half dozen of the other… The problems show up with bigger impacts. Hitting rocks/stumps or banging into sharp hard objects at higher than running speeds, and damage from handling (coming off the car, helicopter baskets, gondola racks etc.) turns the “protective" edge into a 48 rockwell hardness chisel directed straight between the laminates and the base. A split then occurs, as well as a bent edge shoved into the board, with the possible addition of twist/mangling. Usually, the result is a delaminated base/core/laminate and stretched and mangled displaced edge. A non-edge-wrapped board will exhibit similar damage: The board/ski will be mashed at the impact, but the delamination will be much smaller. There will be no mangling of the edge – since it isn’t there. Repair is much easier on the non-wrapped board or ski. Under duress, one can simply slop everything in epoxy, use a couple of tongue-depressors or other sacrificial sticks and vice-grip them together in front of the fire. Ride tomorrow. It might not be pretty, but it’ll work. Contrast this to the frustrating attempts to straighten bent and twisted pieces of hardened steel and reposition p-tex and laminate layers at the same time…. I’ve seem the results from both approaches and always recommend not using tip and tail edge wraps. It’s lighter too…..
