On the left is the United Honshu Fighter I. Right is the Cold Steel Grivory (non-metal) Tai Pan blade. It's a sharp ceramic-like blade. They are almost identical in size, but the angle of the camera makes the left one look bigger.
Looking around at fighter knife reviews I came across the Cold Steel Tai Pan knife. It's on the expensive side though at about $300. So, I found this very similar $35 United Honshu for a fraction of the cost.
I also got the Grivory version of the Cold Steel knife for $12. The grivory blade you might mistake as a rubber trainer knife. You can't use it for that though. It's got a sharp cutting edge. Fast delivery from amazon as they came to my door in one day delivery. Didn't pay anything extra for the fast delivery.
I'd call this United Honshu knife in the middle between the KA-BAR and Gerber as far as characteristics. It's still a fighter knife with double edge blade and a pommel that's even more damaging. It's also a wider blade and it's heavier than the Gerber. The grip is also a bit meatier like the KA-BAR. $35 is inexpensive, but the knife feels very strong and sturdy. It uses 440 stainless. You get a lot of quality for only $35. Plain ole leather sheath isn't bad either, but not as nice as the Gerber MOLLE balistic nylon sheath.
Overall, I'd give the edge to the Gerber Mark II as a pure fighter knife, but there's some advantages to the Honshu. You might prefer the meatier grip, pommel and cost of the Honshu. I think I prefer the better penetrating blade of the Gerber and lighter/faster.
