Sorry Rag, I thought you were asking for a side by comparison, and I don't have a #5-4 any more. If it helps, the #5-4 and the other #5 blade lengths are completely different animals, similar in name only. The #5-4 is made along the lines of the Model 8 or 26; small, light, very compact. Almost a mini. Tom is right, the #5-5 is an awesome knife, and IMO, a better choice. I've had a few light weight #5-5's with a Micarta handle, no end cap, lanyard and/or compass, that were truly sweet. If I was to order another, I'd go with a #5-5 SS/NS/MS/Micarta handle of choice (Rounded Ward Gay if available), and either a lanyard or compass...
