I'm not sure where you live but I know in California assisted-opening knives are legal, even with so many other restrictions. I never leave home without my S&W OTF Tanto blade. I prefer the action on an assisted-opener even though thumbtack foldouts can be opened nearly as fast in a SD situation. As to brand selection I have several S&W assisted openers and they are great products at very reasonable prices, whether AO or Manual. Best of luck with our selection!
