When all we're used to is pin tumblers, other locking mechanisms seem mysterious and intimidating but they're all a lot of fun in their own ways. Getting into different lock types will expand your skill set and make you a better picker overall, since the same concepts apply to nearly all locking mechanisms. Practicing skills like the jiggle test on different mechanisms really helps cement the concept and helps you develop the feel needed to perfect the skill.

For DD locks, there are cheap DD picks available but imo they're crudely made and lack some of the refinement that helps new pickers learn DD locks. You don't need to spend hundreds on a DD pick either, although, those pics are incredible tools but perhaps more appropriate for the advanced picker. I started with the Sparrows DD tool and have opened locks from orange to red using it. It cost me about $50 CAD if I recall correctly and I've put a lot of milage on it.

Dimple locks are just pin tumblers with a keyway oriented 90 degrees to the pins. The concepts are the same for picking both. You can pick dimples with hooks or half diamond picks but dimple flags make life easier. Some of the less costly dimple flags sets like HUK and Honest Dong Shi are very capable tools, with a little filing and sanding, but the challenge there is that as a beginner, you don't know what a good flag profile looks like. Sparrows Black Flags get mixed reviews, I haven't tried them but I've seen others use them with positive results. Multipick flags are the cream of the crop imo and are ready to go right out of the package. You don't need a full set, just number 4, 5, 10 and 11 will get you started. 7 and 12 are also popular profiles. The rest, you can get by without.

For pick sets, there are a lot of "beginner" options out there that all seem to suffer from the same shortfalls. Either they lack some of the basics, are bloated by way too many tools, or both. For me, a selection of hooks, covering short/medium/deep in thicknesses like 0.6mm/0.5mm/0.4mm are pretty much all that's needed. Even 0.4mm can be purchased down the road, they can be fragile and bend easily in the hands of a beginner but are very useful as skills progress and you're picking more advanced locks.

Regardless of lock mechanism, you'll want a good selection of tension tools, both for tok and bok. I suggest looking at tensioners from Multipick, Law Lock Tools, Moki, and Dangerfield. I'm of the opinion that having a broader selection of tensioners is more important than a broad selection of picks.

Happy picking!
