Anybody here familiar with the Case Baby Butterbean? I came across three Baby Butterbeans in an antique store the other day and I am very intrigued by them. I really like the mini-canoe pattern and the knives look to be very well made. The three that I found are LNIB 2001 production. Two of them are bolstered and each has a different shade of blue smooth bone. The third is in green shadow bone. I have found several for sale online, but not these specific models, and I haven't found any shadow bone models for sale. Are these knives collectible and do they hold their value? What else can you tell me about the Butterbeans? Any info would be helpful. Thanks.
