Benny,
It is a solid knife, but as with any knife you should think of the purpose you plan to use it for before selecting. If you are going to choose a WSK style of knife you have plenty of options and each maker has their take on the subject. But ultimately you know why you are selecting a blade and your plans for using it. TOPS is a solid product and I own their Screaming Eagle. I do not own the Tom Brown Tracker nor have I had a chance to use one personally. The reputation of TOPS is excellence and it will do most anything you have the skill to make it do.
There are many, many MANY threads on the Tracker or WSK style knife. Pro's and Con's Success and Failures everyone has an opinion but ulitmately your Cash and Your Decision on how you are planning on using it. These types of knives are a compromise to replace multiple tools. But ultimately for sawing chore a chain saw would be preferred. You use what you have at the moment. If you can carry a chain saw in the field I would suggest it. A pack saw is great and will outperform it. But in actuallity the knife was not designed to out perform an Axe, Chainsaw, gut hook skinning set. It was designed to perform the desired task if you don't have those tools available.
This knife is solid and can get it done. May not be as effecient as the tool designed to do the job but it will get you through it comfortably.
I know you are looking for some guidance on the knife but the fact of the matter is it's your cash You decide if its for you.
Hell I wanted a Beck WSK so bad and couldn't find one affordable I built it and it has turned into an opportunity much more than I ever imagined.
The custom makers I have encountered will probably first ask, What do want to use the knife for and What's your budget? and then they make some suggestions to fit your answers.
There are some great guys making WSK's like: Tim Horan, Mark Terrill, Jurgen Schantz, Roger Linger, Mike Billman(he does alot of reprofiling of Trackers) and I am sure there are others that I am probably insulting by leaving off and I apologize for that.
Good luck with your search.
If we can help further let me know.
