Interview: Ron Kosakowski Proprietor of Traditional Filipino Weapons (TFW)

Full disclosure. I purchased a blade from TFW years ago. Also, I have studied Filipino Martial Arts in the past. I have never met Ron personally and I am not affiliated with TFW in any way.


Recently, I had the opportunity to chat it up with Ron Kosakowski. He is a lifelong martial artist and he is the proprietor of (TFW).

Me: Tell me about the composition of the knives and swords on your site.

Ron: We use a blend of 5160 and D2 steel.

Me: And TFW is the only one making blades out of that blend. Is that correct?

Ron: To the best of my knowledge “yes”.

Me: How do you blend the two?

Ron: We have an alloy made in bar form then we send it from the U.S.A. to the Philippines.

Me: What does that blend do for your blades?

Ron: I believe our blades are some of the hardest, functional knives and swords around – near 60 on the Rockwell scale. They are tough with good corrosion resistance.

Me: And you guys have departed from doing just blades of The Philippines?

Ron: We make mostly Filipino blades and we are making blades from cultures all over the world now and the list is growing. More will be added to the site every year. We have some new blades coming out like butterfly swords and a Fairbairn–Sykes knife.

Me: Speaking of “other” . . . are there other manufacturers out there that are producing blades you like?

Ron: Yes, I like some of the folding knives from Cold Steel.

Me: Thanks Ron. We hope to see more from you in the future.

When you dear reader are waiting for your knife porn fix from TTAK, I recommend heading over to TFW for some good looking blades (and a few impact weapons too).


  1. Wow, that’s quite a website. The blades look great and are reasonably priced!

    Glad to hear he’s not using the traditional steel used in the originals. My father (WW2 Army, New Guinea, Leyte, Luzon) brought back a Filipino knife about 10 inches long with the traditional swoopy blade.

    Looked a lot like this:

    Great souvenir of a lousy time spent in places he preferred never to have visited. But as a blade, it wasn’t much. Even as a kid with no cutlery experience apart from an Imperial Boy Scout knife, I could tell that while it could be sharpened, it got dull very quickly in use.

    Later on, I understood this to mean it had been poorly tempered, if at all, and the steel was something picked up and reshaped from — well, who knows? (Considering the time and place, it was probably some piece of Japanese scrap.)

    That knife disappeared years and years ago, and while I have thought of shopping the ‘Bay for a similar authentic one, I think I’ll just stick with the memory.

    But this site has some very nice cutlery — I may have to rethink!
