It’s every man’s worst nightmare. You've just shinned up a frozen waterfall, finally reaching the top of the mountain, and wouldn't you bloody know it, your Sake bottle's been broken in the ascent.
This is a problem rice wine glugging mountaineers won't have to suffer for too much longer thanks to the latest creation of Portland-based outdoor label Snow Peak: the custom Titanium Sake Bottle.
It weighs less than a pound and can almost certainly be used to club your climbing partner to death, should the need to eat him arise.
Small streams and bodies of water are the perfect places to wash off the blood.
It can be yours for a mere $179.95 (£118).
