I know this has been asked a million times, but this one will be slightly different. Pretty much every suggestion that I have seen in regards to removing black coatings, specifically Benchmade BK1, involves sanding the blade. I'm not willing to do this, primarily because I have done it and it's a lot of work that I'm not interested in repeating and I don't want to round off the bevels on the blade.

I know there will be suggestions of 'just buy the uncoated version'. The knives in question are the H&K series and only offered in coated versions and the Emerson I want to strip.... I didn't want to wait a year to find the uncoated version.

I came across this stripper called Green Piranha 707, and I'm sure it will work on an Emerson I want to strip. I found a thread where Erie Emerson says that his coating is xylan based. However, I can't find any data about the BK1 coating, other than the completely useless description on Benchmade ' s website.

Here is Green Pirahna 707 ' s claims:

*Green Piranha-707 is a high performance, fast-acting powder coating and paint stripper used to remove hard-baked, polymeric powder paints -- EPOXY, POLYESTER, URETHANE, TGIC and HYBRIDs. *And it is effective for stripping other liquid and dry industrial coatings such as e-coats, Xylan, Halar and military epoxy-based coatings.* Green Piranha-707 is safe to use on Aluminum and Magnesium, as it will not attack critical dimensions or tolerances. *Furthermore, its proprietary corrosion inhibiting technology prevents damage to surface preparations such as Alodined and Anodized Aluminum, Chrome, Nickel, Zinc and other plating, as well as polished surfaces.

Formulated for fast removal of all industrial paintsNon-toxic, biodegradable formulaContains no methylene chlorideHigh loading provides extended bath lifeLow odor and 100% water solubleNon-flammable, flash point *>200°FWill not corrode aluminum, stainless steel, copper and brassRemoval technology based on several United States and World Organization patentsLow Cost of Ownership.

Wet paints tested include High and Low Baked water-based* coatings, Polyurethane, Epoxy, Lacquer and combinations of these with epoxy primers. Powders include Epoxy, Hybrid, Urethane, Polyester, etc., Nylon 11, Halar, Xylan 1000 series and more. Perfluoro type of coatings present longer strip times especially when applied to rough porous substrates.


Anyone here ever try using this stuff? It's not super expensive, but I'm just curious if it will actually work. I will probably end up trying it out, and may end up answering my own question.... if that's the case, I'll post my results.

Would love to hear any feedback.
