Hey guys, just bought this on the bay:

dubl duck hair shaper w extra blades - eBay (item 130315409852 end time Jul-04-09 14:58:32 PDT)
Figured at under $10 its at least worth adding to my collection, especially as I love dubl duck. Dunno why. Just appeals to me.
My question is, how well do you think it will serve as a shavette for stuff like travelling, camping, when I have no shave ready razors, etc? It is a hairshaper, but will it be serviceable or am I better of leaving this on the shelf? I feel like because these are the disposable razor type blades it is probably serviceable. Any info/advice would be great.
