    Spec Plus SP-6

    This knife is exactly what I expected it to be. The reason I only gave 4 stars is the rubber handle seems kind of flimsy. This knife, with a stacked leather handle, would be the perfect beater, camp chore, fighting knife.

    Simply put, one of the best knives I’ve ever bought. If you have the means, I highly suggest picking one up.

    The SP6- A thinking man's big basher

    Posted by Lance on Mar 7th 2018

    If the Chimera is a poor man's Randall Model 14, the SP6 is a poor man's Chimera, and actually makes the most sense of all, if actual use is planned. A great large military duty knife for all those abusive chores such knives are subjected to, and nearly unbreakable. It is only a few thousandths thinner than the OKC3S USMC bayonet, and otherwise exact same profile, lacking only the sharpened upper clip and serrations, clip ground to same thickness and easily edged, if desired. Unlike the Chimera or OKC3S, the SP6 is extremely simple and light, 30% lighter than the other two, as nothing but pure blade with a very comfortable kraton handle sleeved over tang, and retained by a hollow crosspin flared as a lanyard ferrule. It fits handily in the spiffy Chimera/OKC3S hard sheath with sharpener and MOLLIE compatible, and friction clip, but the third/upper fastener strap likely will not work. However, the supplied inexpensive supplied sheath is entirely serviceable, being hard lined, double retention straps, and also MOLLIE compatible, also grommets top and bottom for lashing, the belt loop not of much use except civilian belts. As with most issue OKC3S blades I have seen, the various bevels do not meet well at tip, but this does not effect the serviceability of the knife in the least, purely an aesthetic thing remedied by buying the twice as expensive and heavier Chimera. Personally, I am finding I prefer this lighter knife, as catching an opponent's blade with a guard, or breaking a perspex canopy or a head not in the cards of late, and what I want is a big, handy, tough blade, that does not weigh me down. It also is an excellent rough duty military knife for those strap bustin', hacking, and everything else you are not going to do with that expensive play pretty knife, chores, and one of the best values for the money. It is becoming a real favorite for these very reasons, as it is as trustworthy as my most expensive knives.
