Thanks for the feedback. Just to be clear, the Bradley is replacing both a delica AND an endura. I'm wanting thoughts on whether giving up two for the Bradley is a good line of thinking. Also, is the sage a better option than both delica and endura??
Depends on what you want to use it for.
I carry a Sage 1 at the office because it's a great EDC for that setting. Wire clip for deep carry, carbon fiber scales don't tear my pants, liner lock isn't going to have to withstand hard use, etc. The Delica/Endura are more value oriented knives that can be used outdoors - grippy FRN, sturdy lockback, stain resistant VG10, etc. Then you have the Bradley, which is just a monster of a folder with high carbide steel, an extremely strong liner lock, and thin behind the edge. It's very much a work oriented knife, hence the lack of a liner cutout so the liner doesn't accidentally close.
So I would look at it this way: the Sage 1 and Bradley make a nice combo for light/hard use, which is why I'd go in that direction. They both have impeccable fit and finish as well.
That being said, the Delica and Endura are both high value knives, so you can't go wrong there either. So you'd have the Sage 1 for a nice, dress knife, and then the Delica and Endura for a choice of small and big for a work knife.
Also worth asking is whether or not you like choils. The Bradley has a very shallow one, which some people like, some people don't. The Delica and Endura do not. However, if you want a Delica/Endura hybrid with a choil, there's the Stretch, which is my personal favorite out of the FRN models. It also comes in ZDP-189, which is an interesting steel.
