I am looking for some information on this knife and possibly the value

[btrwtr]

Very unusual knife I've never seen before. Do you have any information on it? Does the corkscrew retract into the handle? Hard to put a value on it as I have nothing to directly compare it to but based just on the fact it is a Schlieper knife and has stag handles would put it in the $150 ballpark IMO. Would be interesting if someone knows more about this particular pattern Eye Brand knife.
