I never carry a fixed blade "instead", but sometimes I carry one "also".
When I do it's in a horizontal sheath so an untucked t-shirt will cover it.
These can range from my ZT-0100, to the Kershaw Echo, to the Spyderco, Enuff, or my custom, Nitro-V bladed one by Rob's Razors. I forget his INGO name, I contact him on bookface these days

What is the rose-colored grip one, on the right?View attachment 282609
Here are the ones I have so far. All 100% 6-4 titanium. Some with carbon fiber, some with G10 on the handle, most have real eelskin, most with tradition Jap wrap sealed with epoxy resin.
The Steve Ryan on the right is a sometimes carry. I have bigger fixed blades but they are slow for flow drills.
I have 2 Winklers on my vest but they are stowed for now.
Here's an odd question... if you work where you must wear business casual, would EDC a fixed blade on the ankle? I'm thinking that's the ONLY place to discretely carry a fixed blade.
