Oh man, I totally get that...the sentimental part. I have had to do that too...replace a knife for the memory. In my case, that fact that the knife isn't the eact one doesn't matter - just having a place holder with the same kind makes all the difference. And as far as I am concerned, hearing that this was your Dad's knife is all I needed to know - I think he had great taste! I am glad you were able to find a good one on Ebay to fill that void. 

Thanks for sharing!

Yep.  I completely concur on the placeholder concept.

My dad had a Case XX Folding Hunter (6265  SAB) when I was growing up.  He used that poor thing a lot and then lost it, let someone borrow it, something.  He did end up replacing it, but I am not sure he ever got to use it much at all.  I do have that knife and treasure it despite that it is not the specific knife that I remember in his hands as I was growing up.

I am not personally familiar with the S&W knives, but from the looks of the photo, I have to agree with Lars in that he had good taste!

Kevin - no, the other one.... here are a couple of links sharing the same content regarding the S&W Survival Knife series by Blackie Collins. The link to Fitzwillies.com has some excellent photos of the knives in the discussion, while the iKC link does not. 

I own the models 6010, 6020, and 6030 fixed blades, while the others are on my "Gosh, if only I could afford that now" list. 

Enjoy and be edified:
