Fascinating. It would seem that if you carry a fixed blade, hang it from your belt or place it in your pack (which is where I habitually place a Mora). Evidently this would be a good idea, even if your would not call the blade a dirk or a dagger. Agree?
Sure, why not
As long as you pay attention to length/location restrictions ,
esp if it matches up to your carry preferences,
there is no harm in being extra cautions,
like keeping a copy of the laws (or just references) printed up,
or getting opinion letters from the A.G. or D.A. about extra concerns

In re Luke W. (2001) 88 Cal.App.4th 650 88 Cal.App.4th 650
In light of the legislative history of the 1997 amendment to section 12020, particularly as expressed in Assemblymember Martinez's letter, the apparent intent of the amendment was to avoid criminalizing the carrying of knives that are not capable of ready use because they are carried in a closed, secured state. The usual practice in interpreting criminal statutes requires a strict construction of "dirk or dagger." (People v. Bain (1971) 5 Cal.3d 839, 850 [97 Cal.Rptr. 684, 489 P.2d 564]; George W., supra, 68 Cal.App.4th at p. 1214.) Although they may not have folding blades, small knives obviously designed to be carried in a pocket in a closed state, and which cannot be used until there have been several intervening manipulations, comport with the implied legislative intent that such knives do not fall within the definition of proscribed dirks or daggers but are a type of pocketknife excepted from the statutory proscription.
The object containing appellant's knife fits readily and compactly into the pocket of any article of clothing. And whether housed in a loose or tightfitting pocket, we conclude the knife blade cannot, given its snug fit, be easily extracted from its slot without using both hands: one hand or a substitute vice-like mechanism must hold the container steady, while the finger and thumb of the other hand pull at the designated ridged circles. As such, it constitutes a pocketknife exception to section 12020, subdivision (a).

5) When are Dirks and Daggers Illegally Carried Concealed ?
a) Case Law . Under current Section 12020, dirks or daggers
are considered to be illegally carried only if carried
concealed upon the person. Case law suggests that this is
under the person's clothes.
b) AB 78 . At the request of the Buck Knives, AB 798 also
provides that a dirk or dagger is not illegally carried
concealed if it is carried in a backpack, tool belt, tackle
box, briefcase, purse, or similar container that is used to
carry or transport possessions. This appears to be
consistent with current case law.
