Am I correct that this is the Walther P99 you are refering to?
Walther P99 Tactical Knife - Fixed Blade
"Crafted out of 440C stainless steel, the 11 inch Walther® P99 Tactical Knife is truly a versatile defensive tool. The 5-1/2 inch spear-point razor and false edged blade is partially serrated on one side and promises quick and decisive action with a bite. Sure-grip rubber Kraton® handle provides maximum control and the wide steel guard adds essential protection during thrusts. Comes with the popular Walther® ballistic nylon sheath rigged for boot, belt or shoulder harness carrying options."
In the words of John McEnroe..."You cannot be serious?!?"
And this the Buffalo River?
"Buffalo River knife range has been designed for hunters and farmers. Featuring both everyday working designs along with models for specialist skinning tasks. The range includes both folding and fixed blade models. All Buffalo River Knives use stainless steel blades that are easy to maintain in the field and will retain their edge between sharpens. Handles are made from attractive natural timbers or functional composites for durability and ease of cleaning. Several models of the knives are supplied with leather or nylon protective pouches that provide a safe and convenient carrying mode.

It is good that you are looking to move on from your hollow handled thing since almost without exception they are very poor tools, however, that Walther has not one feature that would make it a bushcraft knife. That knife was designed as a weapon first, almost to the exclusion of any other utility tasks.
The Buffalo River looks a lot better as a utility tool. The blade isn't going to lend itself to wood carving without a bit of work on the edge, and lacks point for fine work, but it appears that it would do well at heavier cutting and splitting. The handle doesn't look bad either.
As has been advised countless times before. Go get yourself a Mora, or if you want something a little fancier one of the other puukkos by Kellam, Brusleto, and Helle. Fallkniven F1s are good, as are the Cold Steel Master Hunter, but both are getting up for £70. For value and quality the Mora can't be beat.
You don't say where you are based, or what you want the knife to do. Bushcraft covers a lot of ground and the views of what makes a good bush knife vary with location around the world.
