If this post seems wordy given the information conveyed, it's only because I am a lawyer by training. As such, consider yourselves warned!!! ;)

So a few months ago, I picked up a small Insingo off the exchange after much deliberation about whether I should get a small or a large Insingo, or even just move in a different direction such as picking up a 21 UG. I read a lot of posts and tried a plain jane as well as one with micarta inlays. I felt like the plain jane had greater potential to me if I wanted to customize it and "make it my own" and so I sold the one with inlays. I began to carry the small Insingo and use it all the while still wondering if I should have gotten the large one instead. I have "largish" hands and so naturally thought the large might be a better fit for me. But, the little bugger grew on me very quickly and soon, thoughts of a large were a thing of the past.

In use, one thing that really bugged me was the feel of the lug when opening the knife. It just felt pointy and made opening the knife with my big thumb uncomfortable. I read lots of posts about how to "properly" open a Sebenza, but honestly, at 50 years of age, I just didn't feel like changing my old habits. Mixed in with these posts were suggestions like, "Suck it up and in a week your thumb will be used to it" and "Sell your knife to me since you will never get used to it." Hidden in and among the silliness was a piece of sage advice--gently sand down the top pointy part of the lug. I did that and what an instant amazing difference! That's what I'm talkin' bout!!! :thumb up: And, unless one looks very, VERY closely, you can't easily tell the difference visually.

So, life is getting better and I continue to carry the knife liking it more and more all the time. Then there comes a point when I have to make a decision--should I go forward with customizing this knife with the intent that I will keep it forever or is there a possibility that I will want something different down the road? In my experience, customization will certainly kill the resale value should I choose that route, so I had to be thoughtful. And if I did customize the knife, what specifically would I do? Custom inlays, overlays, anodizing, stone wash the scales, bead blast the scales, scotchbrite the scales, have CRK do a design of my own making, or do something else? Lots of possibilities, only one knife.

Long story short, I decided to hang on to the knife and settled on customizing it, in part, by using Oxi Clean on the scales. I know this idea has been thrown around in the past, but those posts are so old that the photos are long since gone. I was not 100% sure of what to expect, but it was my knife and what the heck--you only live once! While I know there are many different tastes and this may not be for everyone, I am very pleased with the results and wouldn't change a thing. It's my hope that anyone thinking about this will have a better idea having seen and read this post. Just remember, take things slowly and do what you want regardless of what others think. It is YOUR KNIFE.

So, the idea with Oxi Clean is to expose the titanium slabs to the oxidation process that occurs wit Oxi Clean in the presence of very hot water. The titanium acquires an oxidized layer that can help to protect it and hide some marks from use.

The first thing to do is disassemble the knife entirely. The blade and all hardware are separated from the clip and two titanium sides, which are the only pieces you'll be working with. I washed these pieces with soap and water and dried them off. I then grabbed a pair of latex gloves and gave everything a good rubdown with pure acetone to clean off any oils or residues which might still be present. I initially hung the clip and sides by very thin thread suspended above a cup of Oxi Clean to which I added boiling water until the pieces were entirely submerged in the water (about 3/4 of a gallon). I then let them sit for approximately 1 hour, removed them, washed them off with soap and water and then dried them with a paper towel. While they looked somewhat darker, they were not uniformly darker despite being submerged in the solution for the exact same amount of time. Initially disappointed at how they turned out, I thought that perhaps re-trying the process might enhance their look. Worst case scenario I knew I could always go back to the factory sand blast look.

Round 2. I decided that I was simply going to let the sides and clip sit on the bottom of a dish rather than suspend them from thread as that method was a PITA. I also thought that placing the pieces in such a way that the outside (visible) sides of the pieces were facing up. That way, if oxidation wasn't really taking place on the bottom of the pieces, it would be no big deal. I also opted to use water that was not boiling, but rather superheated by a microwave. 1 cup of water heated on high for about a minute (hot as if I were making a cup of instant coffee) was plenty hot enough for what I was doing. Another hour of sitting for all three pieces with some occasional stirring of the solution and "Viola!", the non-lock side piece was very nice. :cool: I'm not sure why, but the lock side piece and the clip still looked like they could improve, so it was off to round 3 for them.

Round 3 was basically a repeat of round 2 in every way. What I found was that the lock side piece and clip needed more time to get to where I wanted them and the third round did the trick.

It's worth mentioning too that throughout this process, I had the lock face and detent ball covered by some Gorilla duct tape so that little area would not be exposed to the Oxi Clean and hot water solution. I don't know if exposure would have made a difference in lockup or how smooth the knife opened and closed, but I didn't feel I needed to find out given how small that area is and how hard it is to see anyway.

Taking the knife apart was a great excuse to clean everything. Putting it back together went smoothly following the instructions in the sticky at the top of this forum. The knife opens and closes beautifully and now sports what I consider to be an awesome look. The pics are below, but the coloration and effect is more or less subtle depending on the light you are in. Combine that with mediocre photography skills and an average camera and the pics just don't do the knife justice. There are shades of blue/purple, gold, and some slight red and green as well. The lock bar side is predominantly gold in color. Looking at the pics, it looks almost rusty looking, but rest assured that in person, it doesn't look like rust at all. It also does not look like a stark, funky rainbow, but is subtle and classy. It feels as grippy after the procedure as it was before. Again, I know it's not the look for everyone, but I love it!!!

So to anyone on the fence about modifying their $300+ CRK, I say go for it!!! There are some here who aren't afraid to do mods to their users and to you folks, my hat is off. :):thumb up: You folks helped inspire me to do this. Next up are a few words engraved above the lock bar on the back and she'll be all done.















 
Very nice work! I really like the inside of the presentation scale - that bubbling acidic look, very cool.
 
Awesome, I think I might try that with my user small cf insingo this winter when I get cabin fever. I think the colors would look nice on the lock side with the clean CF on the other.

I wonder if there's a known way to get more blues/purples and multiple colors in general. Maybe leave them in the solution longer or more dunks but at less time each round. Who knows. It's odd the lock side on yours needed a third dunk to get a similar look as the presentation scale from two.

The only thing that I could think of that might be in play is that each part of the knife came from a different piece of titanium, quite possibly even from different lots. Only the folks at CRK would know what their practices are, but that is my best guess.
 
That is really nice. I love that look a lot. I could absolutely see doing that to my Umnumzaan.:thumbup:

Well done. Thank you for posting the process and pics.
 
Very cool look! I hadn't ever read about using oxy clean in such a way until now...something I'll keep in mind for the future.
 
That's a nice looking sebenza; I like it a lot, it really looks vintage or something of the kind. I got to get some oxy clean and try this, you can always reblast the handles right? The process really made that knife "yours". Cool, thanks for posting this.

Just to clarify, the product I used was Oxi Clean, not Oxy Clean. Both products exist, but you want the Oxi product. It's a laundry product available most anywhere you can buy laundry detergent. And yes, you can always have the handles re-sandblasted to go back to the original look so far as I know.

Thanks for the compliments too folks. I think if you saw the knife in person, you'd love the look even more. As I said, my pics really don't do it justice.
 
What's the texture feel like? That's the one thing I'm unsure of, it almost looks like it would feel flakey if that makes sense.

Thanks for clarifying the difference in products; I had no idea both were available; I used the oxy kind for carpet cleaning and it worked great, but never seen the oxi one; I shall pay attention to that in the future. Thanks again!!

It does make sense and it does in fact look like it would feel like that (flakey), but it does not at all. In my hand, to me, the texture feels identical to what it was before, or at least very, very close. I only have one so it is not possible for me to do a side by side comparison with an unmodified one in my left hand and the modified one in my right hand. Honestly, if I was blindfolded and had both a new knife and the Oxi Clean one, I would be shocked if I could tell the difference between them based on feel of the titanium alone.
 
Chris, I really like the process you've detailed and the great outcome. I'm going to use that process on my 25.
From what you detailed, it seems like you did not plug the pivot hole. I think I'll plug the pivot, just in case, and duct tape the inside surface of both slabs.
Thanks also for defining Oxi from Oxy.

Best of luck with the process. I'd love to see how it turns out. Please post some pics when you are done.
 
I’m not too pleased on the outcome of my Oxi mod…not in love. I modified Chris’s recipe because I thought I could expedite the process down to one step instead of the 3 he used. I made a stronger concentration of the Oxi powder using a longer period of submersion of 2 hours instead of the initial 1 hour that Chris used.
My result was darker than I envisioned and lacked my expectation of some iridescence. Chris hit the green. Mine ended up in the rough.

I’m contemplating giving it another go by removing the darkened surface via Scotch Brite and then revising the recipe to a slightly more diluted solution for 1¼ hour.

I’ll post pictures if I’m satisfied with results.

That's a great look. I love the colours, it's a shame they're on the inside.

I have done this to a few folders (ZT0560 and a Surefire EW04), but not a Seb yet. Both turned dark with no color, but I scrubbed with a brush while submerged in the solution.

I wonder what it would do to a wood inlay? My beater Seb has ebony inlays, but they would make it near impossible to undo if it doesn't look good.

Greg,
Sorry to hear that your first attempt did not turn out as you had hoped. 2 hours is a long time. I think, though I am not certain, that the colorization of the titanium follows the same progression as it would if you were anodizing. My methodology was to take it nice and slow, do it in increments so that I could easily pick a stopping point at which I was happy. Between each soaking, I would give the piece a though bath in soap and water, let it dry thoroughly, and then check the coloration in bright light.

If you scotch brite it, be aware that you might get the scotch bright texture (somewhat slippery from what I've read) followed by the coloration that you do want. Remember, in my case, I didn't feel the process changed the texture at all. So the texture you start with will likely be the one you end with as well. Just something to think about. Either way, please let us know how it goes.

That's a great look. I love the colours, it's a shame they're on the inside.

I think if you do a search here, you can find a thread or two on some changes kidcongo did to his box elder inlays. I'm not sure what Oxi Clean might do to inlays, if anything, but kidcongo shows just how far one can take things and they still look good. I guess I am just saying that even if Oxi Clean did do something to the inlays, I would still think that there are still a few options short of replacing them.
 
Here is an example of a slightly bronzed Ox job I did. Just did a very light hand rub first. Yes it looks alot better than doing it to the bead blast, but is a bit too smooth for me.





 
I like that bronzy color, so you did a hand rub with a scotch pad I assume? It looks good, I'm being tempted to do the same.
 
and for people doing hand rub jobs, how do you keep the lockbar down and flush with the rest of the scale? I hear there are some tricks, but haven't seen any posts or videos on how to do it.
