I'm not sure how close this is to the RAT4, but please take a look at the Benchmade 515 Rant in D2. I think it's a great design, and at under $60 a great value, as well.

Blade length is 4.5, thickness is 0.175.

You can find them at knifeworks.

I already have knives similar to the Rant. I'm looking for a sturdier, wider and thicker blade with a full tang and slab grips. Thanks for the info though.

There are 40 reviews of the becker BK 2 on amazon.

Just go here.

Dave Canterbury of Wilderness Outfitter/the Pathfinder school - who will soon be in a Discovery Channel series - had an unfortunate experience with one of his becker knives. The handle slabs kept unloosening.

Be a little careful with the Becker BK2 ... though I like Beckers, the BK2's blade is 1/4" thick!! That a massive knife.

I much prefer thinner blades. If I want to chop I bring an axe.

In general I find the thick massive bladed knives just too heavy to carry around comfortably.

I have the Becker BK10 and that is closer to the thickness I prefer (though still a little thick for my taste), but I'm not sure if Kabar has rolled that one out ... yet.

That's exactly what I'm looking for, a thick massive bladed knife. Weight does not bother me. I have plenty of slim bladed knives, now I'm looking for a chopper, as I can't carry an ax.

Hmmm, consider the BK9

Only knife I carry, work or everyday, is my SpyderCo Assist with a bright orange handle. Unlikely to be construed as an offensive weapon (blunt tip) while being a perfectly functional knife.

I've got one that size, a custom job by a local knifemaker. Now I need a shorter blade, as I'm planning a horizontal carry. I'll be driving and walking a lot for several weeks in the countryside and a long knife is uncomfortable when you sit in a car.

Yeah, I have a Fehrman Knives Peace Maker for the horizontal carry role. The Fehrman Last Chance may fit your needs. If you aren't familiar with CPM-3V, it's one of those steels that is seriously tough but still takes and holds a keen edge. Good stuff.

Seems to be a great knife and it should at $240!!! I think I am going to go with the BK2. It's pretty much what I need and the price is reasonable.
