I used to, but I no longer own any "switchblades" as defined by
Federal Law
U.S. Code Title 15C
Chapter 29 – Manufacture, Transportation, or Distribution of Switchblade Knives
Sec. 1241. Definitions

Which I used to own...
Under the FEDERAL exception provided by
Section 1244. Exceptions
Sections 1242 and 1243 of this title
shall not apply to –
(4) the
possession, and transportation upon his person, of
any switchblade knife with a blade three inches or less in length by any individual who has only one arm;
...
This situation making legal under Federal Law to a one-armed person (and I have 2 arms, just one hand, so it'd be an arrest and court .. I'd be the "test case" ) that which is illegal under State TEXAS Law
(not registered under National FIREARMS ACT, so doesn't qualify for that exception, I figured I'd hold onto them, those curios, until they were antiques) but the whole thing was just too silly to deal with, simple is better ...
As I grew older, I decided the novelty had worn off and I broke the springs to render them non-functional, and I bought better knives for carry which were legal under all Federal, State and City laws.
Simple is good.
With the right knife
and carrying method, one can be opened faster ... or as fast as, or almost as fast as, a switchblade.
Still, I won't need a knife until after I use 63 rounds of 9mm, so ... not worried.
See below though

Note for people wanting a "slow to open switchblade"
If you would like your knife open and in your hand faster than people who have switchblades ...
I used to wear my knife sheath upside-down, the knife fell into my hand and I could open it.
About 1989-ish at the Renaissance Festival: Biker dude sees me and comments on it... he had a special knife sheath/scabbard/holster which opened the blade as you drew it.
We both drew, like a showdown (attracted a crowd I wasn't crazy about)
It was close to a tie, but I was impressed with that sheath which opened the blade for you as you draw the knife out ... it like held the blade and as you drew out the knife, it opened.
How it works

There is no law at all against having the sheath open the knife as you draw it out.
I'm not *endorsing* this product/company, I don't own one at the moment (I might soon since I'm pretty sure this is the guy on one of the videos below)
This is the only guy who was ever faster than my upside-down carry
The biker dude's knife sheath was similar in design to

how to make your own (He uses a chicago style screw, but you should use a nylon bearing roller,
or, could use 2 roller-sharpener wheels so it sharpens on each draw

)

Simple and unquestionably legal are best.
