DIY: Ganzo F7551 Cleaver blade mod

PLANNING
Ganzo F7551 Cleaver blade mod
I'm planning to mod the blade of my Ganzo F7551.

You can buy the F7551
Aliexpress: ***HERE***
GearBest: ***HERE***

Which blade shape do you prefer? A, B or C?
"B" would be the simpliest with clean lines but I also want a more pointy blade tip.
At the moment I'm leaning towards the "A" version.  

Suggestions are welcome! :)
I'll acid etch then stone wash the blade after the regrind.

STAGE_1
I took the plunge and I went for version "A".
I started with an angle grinder:

Bench grinder:

Belt sander:

This was my best effort at the blade spine

What do you think?
I'm still planning to stone wash / acid wash it in stage 2.
I have to figure out what sort of acid I should use for a dark / black finish.

  1. Hey Isti, nice idea, a folding cleaver with a hole in the blade is one of the most useless things imho :p
    Anyways, I prefer the second version but I wouldn't make straight lines.
    The spine should have a recurve as a thumb rest and to match the lines of the handle and the front should be convex (if I made that mod).
    What tools to you have at hand? Best would be a belt sander or a bench stone but mind the heat. If it turns bronze, that's okey-ish. If it turns blue then you have a good chance for discoloration from etching.
    What medium do you use for stonewashing? I prefer the round pebbles from playgrounds ;)

    1. Thanks! :)
      I went for version "A" because the blade shape what you described reminded me to my Sanrenmu 939. I wanted something more aggressive. :)

      Tools I used: angle grinder for the rough job then my mini bench grinder / belt sander. I finished it by a diamond file and a couple of sandpapers.

      I have never tried stone washing before. Do you recommend small rounded pebbles?
      I also have to figure out what sort of acid I need for a dark / black finish on the blade.

    2. Great job Isti! I really like the way it turned out!
      Would you mind taking a picture with the blade close?

      I have darken some blades by using some PCB etchant.
      Not sure how darken it could get as I was more looking for a midly dark stonewash but if you're looking for an almost black stonwash, there might be some better options. I just used PCB etchant as it was easily accessible to me.
      Then for the stonewash itself, I tumbled it in my dryer (in cold air cycle) in a paint can filled about 30% with a mix of small/medium/larger River Rocks (commonly found in craft stores) and lubed with a lot of WD40.
      If you do that way, I'd also recommend tapping the paint can so it doesn't open, wrapping it in a towel and run the cycle with a few other towels to reduce the banging.
      Run it anywhere from 15mins to 1h depending on how heavy you want the stonewash to be.

    3. Hi Bruno,
      Thanks a lot! :) I've just added the pics of the closed folder.

      I can achieve the same grey what PCB etchant makes but I want something darker this time. Thanks for the details about your stone washing method. I'll try that soon.

    4. Nice! This is one of those where it looks better with the blade opened than with blade closed. Not sure why, maybe the small flat by the jimping that you've left that breaks the lines??? Anyway, nice job nonetheless.
      Make sure to update once you've stonewashed the blade.

    5. You are right, that would have become a bit like that Sanrenmu 939, except I would have done a recurved spine, then a reversed tanto tip.
      Whatever, your version is absolutely not what I would have done and it's looking great! Good job with the sanding on the spine, that's not a beginner's job :)
      So yes, I like the blade shape and even though I don't like black acid etching, I know it will look cool. I prefer a blackwashed blade, no clue how to do that at home. Afaik it's usually done by painting a blade, baking it, then stonewashing. I'd be scared to ruin the heat treatment so I'd only buy black blades right away, like I've done with my SRM 710 years before there was a blackwashed version (clip and screws were still shiny on that one).
      Heavily dark etched blades tend to smear that blackness onto whatever you cut. I wouldn't eat an apple cut with such a knife, it's just gros and happened to me on my etching mistake with this Ganzo:

      The best result with a Ganzo was this 712 where I made a CF skull crusher:

      I always use ferric chloride by the way.

      Delete
    6. Sure! :)
      I left that small flat there as a thumb rest.
      I also have a CF version, I'll try version "B" on that.

      Thank you! I always keep your warning in mind to stop in time! :))
      I don't want smearing blades that's sure. So a lighter grey will do too.
      That Ganzo G712 / F712 mod looks awesome! Something similar affect would be nice for me.

  2. Amazing work! I don't mind the classic cleaver, its a big bonus when you use in a city, its not aggressive at all its a folding chef knife. I wish there was more knifes designed for cutting food.

    1. Thanks a lot! :)
      Regarding chef style folders THIS Stedemon NOC Chef MT03 would be great with a budget friendly price tag...

      Delete
    2. I prefer the Ganzo design. What I really want is a spydiechef clone, still eagerly waiting for one!

      Delete
    3. I have one of those clones. It's smaller than the original (170 mm vs. 197 mm overall length).

      Delete
    4. That Stedemon is nice indeed, the price tag is not.
      Meanwhile I'm quite glad with my TwoSun TS51.
      Too bad I didn't have enough light to take good shots when I used it to cut chives and dill into tiny pieces. It worked better than my big chef's knife but maybe one day I'd still order an Anselm herb cutter just for its cool looks ;)

      Delete
    5. I like THIS Chinese herb cutter. :)

      Delete
    6. Pretty close to the Anselm, weird though that that one goes for half the price shipped from Germany (but most likely made in China, too).

      Delete
    7. That Chef MT03 looks really nice indeed, but I agree with Endre, the price is steep...
      Why are you saying it's a Stedemon, it looks like the brand is NOC knives.
      Are you saying that NOC is a sub-brand of Stedemon? Id that's the case, not shure why that is as they already have Vouking for their "cheaper" offerings.
      Anyway, I like it.

      Delete
    8. I saw that listed as Stedemon somewhere. At least the pricing is similar...

      Delete
    9. Best photos and best price for the NOC Chef MT03 so far.

    10. Given the full billboarding on the back spacer, it might actually be from Stedemon :D

      Delete

    11. At least the blade is clean. It's still better than the bill board blade of the Stitch auto for example. :)

  3. I did mine a couple weeks ago different shape blade though. Nice work. I did an acid wash on mine too.

    1. Thank you! :)
      What sort of acid / etchant did you use? I might try to do the same but I'm not sure.
      Do you have photo of your mod?

  4. I love it...it is one of my most favorite blade shapes. Very unique with the finger choil and the thumb ramp/jimping. The divot in front of the jimping could be like a "digit stop" like on the Real Steel Metamorph and other knives, especially when choking up with the finger choil. I never liked the original cleaver design but if I were willing to do this mod I would like to get this knife. Well done my friend.

      That "digit stop" was not intentional but after the first try I realized it served as a decent thumb rest. My goal was to keep as much blade width as possible with a sharper blade tip.
      With an opening hole it would look like the blade of the Delica Kahr. :)
