Turned My BB Blade To Satin-Pic

I took an old BM/Emerson CQC7 which orignally had a bead blasted finish. Since I don't own any grinders I had to use a Dremel tool. Started with with a good hand rubbing with sand paper. Then a hand polishing with Mothers Wheel polish. Still didn't come out right too smooth. Went to Sears & bought a Scotch Brite wheel for my Dremel tool. Used the fine & here are the results. I'll try the coarse wheel later to see if the finish comes out any better. If it looks ok, I put the wheel to my Commander.
Sorry about the size of the pics.

Good job... If and when the black coating on my '7 starts looking any worse than it already does I may just do the same.
 
David! You're my savior!

I was wondering if that could be done to a BB blade... I guess I'll have to go buy a dremel now... of course, once THAT'S done, I'm gonna want to zero grind it..
 
Thanks guys for the nod. I got bored & curious so I tried to high polish it before hitting it with the coarse wheel. Man, my thumbs are sore from the hand rubbing & snow shoveling.

Here's the outcome of the polishing. I really need to get grinder/buffer

Damn...as well as shelling out for customs..looks like I'm gonna have to buy me a dremel too.

Beautiful.

Thanks Hilton,

The only difference is a Sears Craftsman Dremel=$29.99, comlete with case, bits & batteries. 10% off if you have one of those coupons.

Manual Labor = Nothing except sore thumbs & blisters.

Emerson Customs = Mucho More

The BM 970s was one of the first folders I bought, back in '94. They were pretty hard to come by in South Africa at the time.
It was one of my most favourite folders to carry until I got the Commanders and Emerson customs.
I recently gave it to a buddy of mine who had been eyeing it ever since I bought it.

Seeing your BM makes me wish I had not given it away

How long did it take you fo each stage of the process?

I have the BM CQC7 (also a '94 vintage, I think - is it the 970?) Anyway, I have a "real" Emerson now, but I'd like to fix up the BM as a secondary carry (salt water and rough use have taken their toll on the blade, not to mention the body. And, I don't think I'll ever get it apart again, because those micro Allen screws are stripped) But, in any case, I'd like to give it a little TLC, 'cause it's been a good knife. So fire away, David! Let us know how ya did it!

Hmmmmm,....if you're still bored....and tired of the snow....I've got an old DeLorean in the garage that could use a shine like your Benchmade has, David.

Man, that is terrific! Looks like I have to get a damned Dremel now.

Why don't you list the supplies and tools and step by step what you did with any helpful hints you might be able to muster.

This could have some serious ramifications.

I could do a LaGriffe, I could get a SARK and have that blunt tip modified to a real rippin' ass Close Quarter Defensive Tool...then polish the bugger up satin.

Could do a Commander...the sky would be the limit.

Talk about giving people hope. Damn, you the man!
 
Supplies:
Sear Craftsman, cordless Dremel.
Different grits of sand paper.
Mother Mag Wheel polish. But I'm sure any abrasive polish would work.
Coarse & fine grit mini Scotch brite wheels for the dremel. (Brown & green)
A good movie to watch while polishing.

This BM was one of my first "Higher End" knives. I carried it a little until I noticed a little spotting on the thumb ramp. I guess from the sweat from my hands. This little incident turned me off to bead blasted blades. ( Except for a CQC67) Couldn't pass that one up. The BM has been sitting in my safe for probably 4-5 years since. I have yet to buy another knife which has BB on the blade.

I had purchased a Commander which was going to be my project knife. I figure I would experiment with a knife I really didn't care about first before I wreck a brand new Commander, thus the BM.

Like See2 said, Those pesky micro allen head screws strip easily. I stripped two of them. Had to extract them with an EZ out. Went all over looking for replacement screws. Home Depot, Sears, even Kmart. I finally gave up & emailed Benchmade for replacement ones.

Took the knife apart. I first sanded the blade with fine sand paper until most of the BB was gone. I then used a Dremel & Mothers polish to polish the blade. Be careful when using a Dremel with polish. It throw the polish all over the place, walls, ceiling, wife, onto the nosy dog investigating the noise from the dremel, etc.

The blade didn't look right probably because I didn't go deep enough on the BB. I sanded it some more. Got tired of sanding & bought a mini scotch brite wheel for the Dremel. This worked great. Got the finish I was looking for, but the grains are a little too fine. Then as I mentioned, I hand polished the blade again for literally an hour to see how it would look. (Pictured above) I'm not sure I like it, so I'll probably try the coarse wheel tomorrow.

You'd be amazed at how roughly finished the steel is under the bead blasting. There are deep scratches & actual tiny pits in the steel under the BB. I know I didn't cause them as I never put anything hard enough to the blade which would cause pits & deep scratches. The BB hid these flaws. I guess that's why manufactures use coatings or bead blasting. It saves time & money on the final finishing of the blade. No buffing or polishing, just coat it or BB it. This is probably a topic on its own.

Anyway the entire process is pretty simple. I'm no rocket scientist. Just bored. All it take is some elbow grease. It would be a heck of alot easier if I had a grinder which I could put a larger, coarse Scotch Brite wheel on. It would cut out the sanding, polishing, & re-sanding process.

If I get good results tomorrow with the coarse wheel I'm going to do the same process to my hard chrome Commander The Commander will probably be easier as I don't have to go too deep to get rid of the BB. But then again, they don't call it Hard Chrome for nothing. We'll see.

Eric: An old DeLorean...hum, I think I'll need more then a Dremel for that project.

Sorry for the long post. BTW, use goggles when using the Dremel. I got that from the instructions which came with it & polishing compound hurts like heck when you get it in your eye
biggrin.gif
I think I can actaully see better out of the eye which got the polish. It buffed my cornea

BTW, I'm sure most of you already know what a BM CQC7 looks like, but here's a pic of it before I started screwing with it.

David,
Beautiful job. You are truly a man of many talents...I hereby dub you our "Renaissance Suspect." Just one question though...when are you going to start taking orders to regrind blades so as to eliminate the secondary bevel? Happy New Year.

Once in a while you get shown the light
In the strangest of places if you look at it right.
 
Laseman: I'll gladly accept you knife to play with the next time I get a weeks vaction; which is Decmeber 23 of 2001.

Jackstraw: Glad to have you back. As for regrinding blades...hum? If I attempted to grind a straight line/edge, the egde would probably come out with the curves of a Commander.
biggrin.gif
I humbly accept your title of Renaissance Suspect.

I'll post the Commander when I'm done with the blade. I really appreciate your support guys.

I took the secondary bevel off of a BM Emerson once, with a coarse, medium, and then fine stone set and a lot of bench time. The resulting edge was VERY sharp and VERY thin. Not worth it. I don't own a custom, but I think the angles end up different. Big time different.

Well here's a status report on the satin Commader project. Now I see why they call it HARD Chrome. The Scotch brite wheel barely put a scratch on the finish. Here's a pic of the blade after an hour of hand sanding. It takes forever just to get down to the bare metal as seen in the picture. This blade is going to my friends house who has a grinder & King Bur belt grinder.
