DIY Blade/metal coatings - using Alumahyde II on knives - results inside.

Hi all,

I've noticed something of a trend in my knife collection, and it is that I cannot stand fingerprints on my satin knife blades. So I went in search of a way of coating folding knife blades that would be somewhat better than Krylon. Enter Brownell's Aluma-hyde II. This is a coating that is somewhat similar to a Duracoat, but comes in a ready-to-use aerosol can. Having used this coating on my shotgun, I know that is relatively durable, and can look good provided that you do the proper prep work. And plus, summer is the time of year to use it since HEAT helps the curing process.

So as a test I needed a donor knife and I chose two - Chinese cheapies - the Ganzo G714, and the Enlan EL-04. This thread will only cover the EL-04. Perhaps I will make another thread or post later about what not to do, mistakes I made on the Ganzo G714.

Enter the test subject:

The Enlan EL-04, an axis lock knife that has identical handles to the Spyderco Manix 2; Combining two great designs from two different knife companies.

I chose to use Matte Black color on the blade and pocket clip, for that tactical look :o

Disassembly was easy with a T6,T8 and specialty "triangle hole" wrench. Luckily none of the hardware stripped out.

You will notice the extra nozzles for the aerosol can, these are absolutely necessary with Alumahyde II, as the standard nozzle will instantly clog no matter how much you shake the can. the clean out nozzles are a life saver when this happens.

Cleaned the parts liberally with mineral spirits to remove any residue and left to dry.

I then put the blade in the oven at 200 degrees for ten minutes, just to heat up the steel; heat really helps adhesion with Alumahyde II. I did not do this to the pocket clip due to absent mindedness.

I then hung the parts and sprayed several light coats only minutes apart, drying with a blow dryer between each application. I recommend you do this outside or inside a spray cabinet to contain the overspray mess. (wish I had taken pics of this process)

When you feel the coverage is complete, then comes the curing process; a looongg wait. Some recommend waiting up to a month to allow the Aluma hyde II to completely cure and harden; Some put the coated pieces into the oven at low temperature. I did the best of both worlds - I left the coated pieces in the hot car parked out in the sun for several days, then hung to cure for about a week.

Result:
Aluma-hyde II is a thick coating, you can see the texture here:

The pocket clip will be the test of wear and tear:

After resharpening (the coating took more than a few passes on the stone to completely remove):

EL-04, tacticalized:

there is some residue on the blade here, dust from the sharpening stone.

And just for giggles, here is my shotgun I Aluma-hyded over a year ago with OD Green:

Hope this was somewhat informative. After this process, I don't think I will do it to higher valued knives, as trying to remove this stuff if I mess up or change my mind would be a nightmare :)
 
Good read and picz. Thanks for sharing with us. Please if ya got the time or remember.... update after heavy use so we can see the results from use. Looking forward to how it holds up to lots of use.
 
Very sweet application I think I am going to do this for my big knives to give it a test of durability.
 
Did you protect the pivot/detent holes prior to coating? Seems like it might be an issue.
 
The EL-04 does not have a detent hole, so that was not an issue for that knife. For the Ganzo 714 I there is no difference in blade retention. I coated the entire blade. A small change for the future might be to use tape to cover the parts of the blade that make contact with the lock surface, as those sections of the covering have worn away. Both knives still open as smoothly as before.
 
Will you post a couple current pics so we can all see hot the finish held up?
I took a blade in a couple years back and had it miracle coated-lasted less than a week with use. Not interested in doing that again with this material :)Thanks,
Dave
 
I almost forgot about this thread.

A quick update though, under hard use the finish does wear off, and I think given the amount of prep work required there are better alternatives for an often used knife.

I ended up trying this on the Enlan EL04, Ganzo G714 and a Kershaw Tension.

I will update with pics and maybe a video later.
 
Ok, it has been a while, I made a video so you can see a bit on how the Aluma-Hyde II was worn over time. Sorry the video is a bit longish.

It looks nice, but black oxide or powder coating would be much faster with about the same results.

I have never used those, but probably so! I am now curious to see how the Aluma-Hyde II would hold up compared to your basic Krylon that people use to paint their gear all the time. Perhaps a topic for another experiment.

Krylon is a JOKE compare to AlumaHyde II.

AH is very tough.
Not harsh chemical resistant. Acetone, Brake Cleaners...
Goes on thick.
Buy extra nozzels. They tend to clog.
When you think you have shaken the can enough. NOPE add another 10minutes.
you better wear a resperator.

OP.

I have gotten better result by preparing the steel in the following manner.

sandblast then parkerized

Or Sandblast and follow up with Jasco Metal etch.

as for the clip.
I dont think there is any thing out there that will not get
buggard up.

and yes I used it.
But now I prefer
Norrells moly resin
or
CeraKote.
 
Yes, there are better alternatives to Alumahyde II, but what is good about it is that there is no other gear required. All that is required is the rattle can itself, and some extra nozzles for it. This lowers the cost of entry to use the product. Kind of the poor man's Duracoat/Cerakote.

Anyone can send a knife out to get professionally dura/cera coated, but I wanted to see what the average joe could get done at home themselves. But you are right about the surface prep. Success using Alumahyde depends completely on how well you prepare your parts before coating them.

Look at the Kershaw Tension I coated with the Park. Grey color. On that knife I did NOT preheat the blade to help with adhesion, and see how much it wore versus the Ganzo G714 that was preheated. A big difference, and I am glad I did it that way so we could see how it changes the end result.
