Great little knife

Great little knife, I monted it on my console hose, It is on less thing I need to remember, and it is in a spot where I can get to it quick if I need to.


Most Liked Negative Review


not a BCD knife

I was expecting a knife that would attach to my BC. This knife has an open-ended clip like you would see on a boot knife. It also comes with a fitting so you can attach it to your hose. But this is not a BC knife; it's a hose knife. Zip ties are your only recourse if you expect to attach it securely to a BC.

Nice dive knife


from fortuna, CA, US

Short but built well. Fits along bc very well. Easy to lock or remove/replace.


Tiny! Not sure you'll ever use it?


from Palo Alto, CA, US

This is a nice, tiny little dive knife. I attached the belt clip and tossed the hose clip which I now regret. The steel in the belt clip is very weak and bends easily so it doesn't attach securely to anything. For now, I have it attached to my big blue dive light wrist harness. I sandwiched a piece of the harness between the belt clip and the sheath and then screwed on the belt clip. Seems very secure! However, I am coming to the conclusion that you don't need to dive with a knife. Seems like shears would be better for most things like entanglements. For hunting I suppose you would need a pointy tip and if you tried to lever something with this tiny knife I'm guessing either you or it would break...so if you know this is what you want and you want to attach it to your inflators hose, this is great. Otherwise, maybe go for shears? In 20 dives, I've never used either.


Good Security Blanket


Since I often dive alone I need to be prepared. I don't expect to ever need this knife, but I'll be glad to have it if I do. It has a secure locking sheath so I don't worry about losing it and a reliable hose mount. The curved grip is easy to hold. The blunt tip can be used as a screwdriver if needed and seems safer to use in a situation that could be harried if I ever get tangled up.


Small but high quality knife


I bought this to use as a primary knife while recreational diving, and am happy with the quality and size. It's a little smaller than most knives (I can't wrap my last finger around the handle when gripping it), but I like that it's easier to pack and carry as a result. Also consider the BCD knife attachment (sold separately) if you'd like to screw it to rivets on your BCD - it's a nice combination.


well made knife


I have not taken it diving yet but the knife appears to be a very well made blade. I'm not to sure about the release mechanism though, seems fragile and may be difficult to release knife with gloves in cold water.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
LARRY L  I wanted a knife that attached securely (with screws) to a BC hose and that was easy to remove and replace in the sheath. Also, the sheath has a positive lock so the knife won't get lost.
CHRISTOPHER C  Awesome little knife, especially when used with the hose mount-- works great
JOHNNY J  Tusa is the only brand dive knife I've used that never rusts, even with just rinsing my BCD with my knife inside.
EILEEN J  I don't need to carry a huge knife and this one is perfect for having a knife in case you need it.
PHILIP P  Works well so far, have it mounted to my low pressure hose. Locks in the sheath securely, no rust yet even after salt water. Just remember to remove the knife from the sheath if you take your reg's on board with you otherwise you won't be making your flight!. I actually have a small box to store mine in in my checked baggage.
RAY T  It seemed really compact. The only problem I've had is that it's a little difficult to get out of the sheath with gloved hands. My primary knife (strapped on to my leg) is much easier to remove from its sheath.
MICHAEL B  Fantastic BCD knife. If you attach it to your regulator, don't forget to remove it before you hand carry your regulator through airport security. Oops!
LARRY L  How does the locking mechanism release? What do you press/where is it located?
DOUGLAS S  pushing a small button towards your hand, slightly awkward.
Angelo F  The hose mount mounts to the casing.... the Hose mount is a C clamp the has a knob which secures it...
MICHAEL F  It is a button that slides up toward the handle to release it. search for "TUSA Mini BCD Knife" on youtube. There is a video showing how it works.
RAY T  The locking mechanism is located on the sides of the hard plastic sheath. The knife snaps into the locking mechanism. To release the knife, just push both buttons with your thumb and probably your first finger. Just putting the knife back in the sheath will snap the locks into place. I dive in cold water and can easily do with with my dry gloves on. It's really a nice mechanism.
MARK L  There is a small black button at the base of the sheath. When you place the knife in the sheath the knife clicks into place, then you push the button forward (toward the tip) for another click that locks the knife in. To remove it, move the button back toward the handle (another click) then pull the knife out of the sheath. It's very easy to do just by feel, and the sheath holds the knife very securely. Great small knife!
LARRY L  Does the hose mount use screws to attach?
Angelo F  The Locking mechanism works by twisting the knife and pulling ...
MITZI A  Yes, mine could attach either by clip or with the 4 supplied screws to the hose
STEVE C  Yes on the screws - However, I am member of police dive team and our diving is pretty rugged so I used tie-wraps (plastic) instead - I attached the scabbard directly to the inflator hose withOUT the special adapter.
TORI S  The screws attach the knife to a plastic piece that encompasses the hose.
MARK L  Yes. If you look at the picture of the belt clip attached to the sheath, there are 4 screws holding it on. To use the hose mount, you remove the belt clip (which I would never trust anyway). The hose mount aligns with those 4 holes, and you use the same 4 screws to secure the hose mount to the sheath.
CHAZ E  It does use screws to attach. It is very secure and low profile. The knife itself "nicks" into the scabbard and is held very securely. I have almost 60 dives with this knife and never had a problem with hoses or other gear getting caught up on the handle. Best insurance you could ask for in case you need to get untangled from some fishing line, nets, or other underwater snags. Glad I've never needed it, but glad I have it just in case.
