Well it would be fantastic to have all of them so you could pass definitive judgement

But the Norfolk is a fine pattern
Trust me, it's not for lack of trying!

I've been on the hunt for an ebony Norfolk for years! I always just miss out when one pops up.
Here's what I have had go through my hands with a quick comment on each.
Ebony WT - Great size for EDC. Ultimately I love the looks of the pattern but didn't care for the feel in hand with the clip blade deployed. The wharncliff really digs into my grip.
Dogleg Jack - Also great EDC size although pretty beefy and feels like a brick weight wise. Love the spear main on this one! Literally the only reason I didn't keep was because I just don't like a downward arch on my knife blades. If the tip were more centerline with the handle it would have been a keeper for me.
Chestnut Coffin Jack - Sweet little knife. The smallest of any I've owned. It didn't blow me away as far as usefulness which is probably why I sold it but it was so good in F&F you could have swore it was full custom.
Chestnut and antique bone Lannys - Awesome knife but for some dumb reason I sold off both. Probably should have kept one but I must have been chasing something else at the time. Oh well!
Ebony Eureka Jack - currently in my collection. Sold my first one. Missed it so I bought one in bone and then had Javi Garcia recover it in micarta. Wasn't completely happy with that so sold it and now I'm back with an ebony version. Really a great EDC. I like the little wider main as compared to the Coffin Jack. I also love the contoured frame on this one. 3rd times a charm here. This one will be a keeper!
Ebony Cattle Knife - Best production slip joint ever IMO. For me nothing I have ever owned, custom or production comes close to the value, quality and bang for buck that you get with this one.
