The loop part of the hiplok DXC would probably take 5 minutes to cut with a battery angle grinder. The cable part appears to be no better than the master/amazon/ebay/bike-shop cables with extra flexible (tiny) wires that could be cut by a $20 7" diagonal cutter in about one minute. My SS mcmaster 1/2" sling would take 30 minutes to cut with 7" diagonal cutter. I tried cutting a SS cable the city left laying on the ground by a traffic light. Made of thick SS wires, cutting each wire individually took 6 minutes to cut one strand. There are 7 strands. I estimate a $50 harbor freight bolt cutter would be severly damaged by the mcmaster SS 1/2" sling. There is a $280 SS capable 1/2" cable cutter at mcmaster, but no thief is going to buy one of those since I'm the only person that ever used a SS 1/2" sling to secure a bicycle.
Frustrated thieves have knifed my tire twice as my bike was parked on the street. One stole my tool box, but none has ever knifed the spare tubes or tire in the pannier.
