This was discussed around here a lot several years back. The conclusion seemed to be (per Mr. Cotton IIRC) that the intention of the legislature was to make §46.02 non-applicable to CHLs for handguns only.

From the San Antonio municipal ordinances:

Sec. 21-17. - Certain knives prohibited generally; exceptions; penalty for violation.

(a)It shall be unlawful for any person to intentionally or knowingly carry on or about his person a knife with a blade less than five and one-half (5½) inches in length, which knife is equipped with a lock mechanism so that upon opening, it becomes a fixed blade knife.

I'm not sure why they want to outlaw a basic safety device for knives, but my conclusion is that if you want to carry more than a Swiss Army knife in San Antonio you have to carry:
1) a lockblade with blade exactly 5.5" long (note SA only prohibits blades less than 5.5". and state law only prohibits blades over 5.5"), or
2) a fixed blade (within the limits set by state law obviously).
