What about SOG Bi-Polar (Serrated) BP-3? It has two blades - one plain and one fully serrated. Plus it has glass breaker.

I don´t own this knife so I can´t say if it´s good but it´s on my I-might-buy-this-in-the-future list.

Good call raptor man!

Only downfall is no pocket clip! I wonder if one can be adapted.

Yeah, it´s a pity it doesn´t have a pocket clip. Anyway wouldn´t this knife be too heavy for ED pocket Carry? I, myself, tend to prefer thin and light knives when it comes to pocket carry and would consider this blade as a backup carried in the backpack etc. but a lot of people don´t mind the weight.

Thanks, all, for the comments. I don't yet have my replaced knives as my mail situation is complicated, but I am looking forward to getting them.

The clip on my Spyderco Dragonfly (the FRN model, a plastic clip integral with the scale) broke off while it was in my pants pocket clipped to the edge of my pocket. I was lifting and bending and moving things and I never found the broken clip, just found the knife in the bottom of my pocket with a jagged stub. This was unusual behavior for me, as my work days are suit and tie, so the knife was only lightly used.

Unfortunately, there don't seem to be any alternative Spyderco models in the same price range or less as I prefer a traditional lockback and not a liner lock. I realize the Ladybug is small, but I am hoping that the serrated edge will nonetheless be handy. I'll likely put a Bug on my keychain as my work knife (even the Dragonfly got some surprised looks from coworkers) and drop the Ladybug in my pocket on weekends.

Cheers,

Matthew

I have an original Endura and Delica, both with the plastic clips. They're almost 15 years old now and have held up pretty well. I probably carried each of them for at least a year's worth of days without breaking the clips. (Of course, the newer models are metal clips.)

Now I carry the Spyderco Caly 3, plain-edge with G-10 scales. It's a bit expensive (I paid $75 a few years ago), but it's an awesome knife. With more of a flat grind than the saber grind of the Delica and a little "convex edge" sharpening work, it push-cuts better than anything I've ever owned except maybe fresh razor or X-Acto blades. The wire pocket clip worried me at first, but it really doesn't feel or look as cheap as I thought it might. I really like how low it hangs, especially since I usually carry it inside my waistband instead of a pocket.

I should mention that I stopped carrying clip knives clipped onto pockets several years ago. The clips were always catching on things. Now I usually carry inside the waistband of my pants, with the clip underneath my belt. Very little of the knife is visible and it's almost impossible to snag the clip on anything. It's also been a lot easier on my pants - I was wearing out the corner of all the pockets. If I'm actively working on something where I might need my knife quickly, I just move it to the pocket then.

Sorry to hear the 'uk legal' spyderco isn't up to scratch. So is there any way to carry a locking one handed opening knife in the UK?

I'm with Ratbert, I've had my Endura at least 15 years and the plastic clip, the whole knife is still top notch. I don't think I've even sharpened it in a decade its still one of the sharpest knives I own.

Well, you can carry anything if you can justify good reason - but as routine edc then no. I find the Byrd wings slipit works fine though for a lot of jobs, or there are friction folders like the Svord peasant - get the friction tang under your hand and its not going anywhere

I was about to say, "I remember a kind of non-locking folding knife from the Ragweed Forge," but it appears to be the same Svord peasant knife mentioned by bigreddog.
