Hi Lance,
Love your knife! I have a Pac Salt serrated, and a leaf PE Caribbean, and I haven’t carried either since picking up the Siren last month!
I prefer the wire clip, larger guard, and lack of a typical Spyderco hump. I didn’t think ergos could get better than the Caribbean, but your knife is even more comfortable! I have a few thoughts after carrying this knife daily for several weeks.
1. I had to sand down the G10 slightly, particularly under the clip. I appreciate the aggressive texture for increasing grip and safety, but it was just too hard on my clothes, and sometimes too difficult to extract the knife. It’s probably better to start too grippy, because you can always sand it down, while it is much harder to go the other way around.
2. I ground a small sharpening choil using the corner of a Sharpmaker rod. My knife free-drops when unlocking, and I had a few very close calls with the edge coming against the skin of my index finger when closing the knife. I assume you wanted to maximize the edge length, but my index finger is much safer now that the choil is there. This mod only uses up 3-4 mm of edge.
3. Surprisingly, this was the dullest Spyderco knife I received out of the box, and it was a brand new one. I own or have owned some 15 Spydercos, dating back to the late 90’s. Not a big deal, as I resharpened it immediately, but this was unexpected. I haven’t seen this comment on any other Siren threads either here, or on the Spyderco forums, so perhaps it was a one-off.
In summary though, this is a spectacular knife, and I’m very glad you made it!
