I got one for myself about 2 weeks ago after about a year of procrastination, and I can easily say it is the best engineered, best built, "production folder" I have ever seen.
Have you ever seen a "production" knife that has absolutely NO play in any direction when opened?
The action is super smooth,(although I don't like the smooth thumbstuds, and that is being addressed
).
It has a 1 piece T-6 aluminum handle (1 piece, as in NO seams
).
The blade is 154CM, which is well known for it's cutting and edgeholding abilities,and it is ground pretty damn close to perfection and finished off in a polished stone wash finish (looks real cool).
And it comes in some really cool looking colors.
You mentioned the William Henry line. Well I have had a few and I even kept one that I had filework done to, and while they are superb knives, they are not the same type of knife, so it is really hard to compare them.
You also mention Sebenza's. While the Sebenza is a very finely crafted and sturdy knife, to me it is more of a utility blade(which is not a bad thing)than the Synergy. You can't really grip the Sebenza in a reverse grip and expect to accomplish any slashing moves. I am not knocking the Sebenza, but it just never "floated my boat".
You also can compare it to Microtech if you wish. While the MT Socom or Kestrel or Vector, etc,etc. are all vey nice knives, they do not come anywhere close to the fit and finish of the Speedtech. I have had and sold many MT's and so I feel I can speak from experience.
The way I see it, the Synergy is a more precisely made and functional knife than MANY custom knives I have seen, and for a lot less money. I have made mine my daily carry, and I don't see anything in the near future that will take it's place.
I might take some heat from the Sebenza and MT purists, but I would gladly compare a Synergy side by side with any of them. And just so you know, I do not willingly give praise to ANY thing very easily, be it knives, guns, cars, etc., so they must be doing something right.
Oh, and one other thing. Jim O'Young is a very easy guy to do business with. He seems to really care about his product and is willing to stand behind it.
Get one, you won't be sorry.
