like I wrote earlier, Spyderco police for folder. Slim, great blade (4 inches +), excellent jimping and finger choils for great control.
If you are going to opt for a fixed blade, look at the Spyderco street beat. You can wear the sheath inside the waistband and forget the knife is there (check local laws). 3 1/2 in. VG 10 (same as police model) blade, razor sharp. BEAUTIFUL knife. Contoured Micarta scales. Deep index choil for superb knife retention. Excels in the kitchen too...:wink:
