Speed Bump Aluminum Handles (1595ALBLK) BIG Pictures

[tom19176]

thanks for the pic....where is the torsion bar? Why did you open it up?

Sorry to have been misleading but this is the Santoprene/Akulon (Plastic) handled regular 1595 Speed Bump. This particular Speed Bump (for those of you who have not read my magnum opus on public urination) was repeatedly opened with centrifugal force (wrist flicks,) not by myself, which caused the Torsion Bar to fail. I decided to open up the knife to remove the bar which rattled about and would occasionally catch on itself. Removed a little rust on the blade with an eraser, while I was there. The ball bearing falls out very easily--watch out for that sucker.

Interestingly the steel liners have the series of 4 "onion holes" and what look to be holes for dual torsion bars--if i'm not mistaken. I can only dream. [edit] okay maybe not, but it's a nice idea.

While reassembling the Speed Bump and replacing the torsion bar, one of the little brass pins that are on both liners (see picture #4) fell out of the knife and i managed to lose it. I think these are held in place by friction. So anyone disassembling their Bump, watch out for those and the ball bearing.

You're photo skills are awesome. I'm a madd Bump fan as well. 2 Aluminum, 2 G-10, 2 Titainium, and 2 Plastic. I don't really like the way the plastic feels, but it works perfectly. I back filled the scales with hot glue so they would feel more solid and painted this one. I have my other plastic one apart and I am currently trying to make my own scales for it. But so far all I have acomplished is a healthy respect for what Kershaw is able to do at the price point they deliver at.

I have a similar1595AL. One with polished blade, clip, and scale edges. The other with a polished scale face and a S30V blade pulled from one of my SpecBumps.
Anyway, Madd props going out to you rottwang

Opps, doubled up.

What? No, no, my photography abilities aren't anything special, i took the pictures with a lot of light and as closely as i could. the Camera did all the work!!

I need to try filling the akulon handled bump's scales like you did. Are you satisfied with the hot glue? looks like you really use that knife a lot!

CUSTOM SCALES! yes!
When i saw that the liners on the Speed Bump had "Onion Holes" I got the mad idea to get some walnut and whittle my own scales (just like Cub Scouts... ah, the nostalgia.) Except i don't have any woodworking tools for making the shallow depressions for the assisted opening torsion bar, or for the holes for the screws. I'm sure I would have to be very exacting and couldn't just take any old pocketknife and crudely grind my way through a piece of wood expecting the screws to work afterwards. What are you thinking of doing for custom scales?

Hmmm wow you've got something great going there. the Aluminum model with polished scales? i was thinking of doing that the other day, but then i'd compulsively have to polish the blade to a mirror finish to go with the handle and clip.

Looking closely at your 1595AL knives i can see that they say "Made in USA" where mine does not. weird.

seems we both live in SF and like the Kershaw Bump. glad to find someone with so much in common

The hot glue was fun and easy to avoid getting it in the torsion bar slot. My first try was Bondo, but some of the fill areas are so thin that the Bondo just flaked off. The hot glue was easy to sand flat after it cooled. It didn't add as much wieght as I would have liked, but it feels way more solid and doesn't have that hollow plastic sound upon opeand closing. The used look is just me grinding my blades. I experiment a lot with different finishes: Polishing the satin, buffing the DLC, that one was sanded at 180 grit and left that way. It ended up with an odd 3D gleam so I just stopped there.
It was nice to see your posts; sometimes I fear that I am crazy... knife crazy, but at least I am not alone. Thanks ; )
PS is there spellcheck on this forum, because my internal spellcheck is from the 70's.

So far I've tried printed circut board, plexiglass, solid plastic, and now I'm onto laminated aluminum. The cuts for the speed safe torsion bar have proven harder then I thought.
I may turn to casting resin, or better yet, buying more knives with great handles from Kershaw.

I love the design, I'd buy one if it was a liner lock or frame lock.

?ave you tried stud lock yourself? Its very easy to operate.
Speed Bump looks muck nicer with Al handles - the only thing I didn't like was its "fat" profile.
