I will put in my two cents as well. A few have posted som comments that I agree with, but I will restate as needed:
First, I will say that the knife is generally a beautifully made knife and a VERY "nicely made" knife for $50.00 with fine attentions to "quality" details.
One exception (IMO): I purchased two and both have fairly roughly finished liners. I would prefer smoother finished sides of the liners.... But, for $50.00..... I can't complain about the finish on the sides of the liners.
If this knife had a simple liner lock, I would value it at well above $50.00. The build quality and material quality by themselves should put this knife at well over $50.00, but for me, certain functional details bring down the otherwise much higher value.
I (personally) have "some" issues with some of the design features. But, quality is top shelf and for someone who wants a fun to play with knife, with exceptional materials and build quality, this knife is hard to beat for $50.00.
Details:
Materials: I love the CF scales. The look and feel are both awesome in my book. I like them better for folders than G10 or micarta and easily nicer than any type of plastic or rubber variations. I haven't owned CF scales prior to this knife and have owned hundreds of folders. The CF scales may have just become my favorite (for certain folders). I think they are the best looking folder scales I have seen and the feel is just right IMO. Just smooth enough for a pocket knife and just enough grip for what I want and expect for a pocket knife.
But, I don't think I would want CF for (most) fixed bladed knives.
S30V is a great knife steel in my book. I don't feel I should have to go much into that. Most people here know enough about S30V.
Quality: Generally "TOP SHELF". The knife is VERY nice looking, Very well made and with best materials. I am VERY impressed all around..... except for as mentioned above: the sides of the liners are rough and I would prefer they be smooth and flush with the scales.
Design: The handle shape is very good. I don't know that I can say it is my favorite handle, but it does fit my hand very well and quite comfortable. I like the choke up on the blade..... turns out to be VERY neccessary for this knife.
Sorry for committing any blasphemy here, but..... I am not the biggest fan of Spydie holes. I prefer thumb-studs. I generally prefer opening folders with a thumb-stud, but my biggest issue is the incredibly large hump on this knife. I am O.K. with some types of thumb ramps or humps, but the Spydie hole and hump on the T-Mag are HUGE and do not feel good or right in my hand for "Use" for me at all. And with the very weak magnet, this blade and knife and especially with the very large "Hump" that is fairly hard to avoid putting thumb pressure on - bring new meaning to the term "PRE-BROKEN" knife.
Maybe I have long thumbs (????). The jimping is on the back side of the hump implying that you would have your thumb on the back side. This is a little cramped for me. My thumb naturally falls at the top of the jimping to the top of the hump. I guess I prefer no ramp or hump to offer more thumb versatility.
But, no matter where I put my thumb, for me, I can't "TOUCH" the thumb ramp on the T-Mag "anywhere" without the blade partially closing/breaking in use. The index finger notch does a sufficient job at keeping the blade from closing on my finger (luckily). But, the blade moves up and down way too easily for most of my preferred uses even for a "Slippy" knife. I happen to like to have my thumb on the blade for many types of cutting chores. But, I find I have to keep my thumb completely off the blade to avoid my blade partially breaking and moving up and down 5-15 degrees all over the place.
I have owned many non-locking folding knives over the years and NONE even come close to the blade movement of this T-Mag. (**** And I am not talking about blade "Play". My two T-Mag's both have dead-centered blades with very little blade play. - EXCELLENT on mine.) I am talking about the blade partially closing/breaking about 5-15 degrees with use when my thumb "touches" the blade. I find this much blade movement annoying - even if my index finger prevents the blade from closing.
If the large hump didn't exist, there would likely be less pressure on the blade which would likely help prevent the blade from always moving when touched by my thumb (?????).
In the end, I think the T-Mag would be a MUCH improved user knife if it had even a very light tensioned liner lock.
Clip: I love the simple, attractive and discreet clip. I actually think it is one of the nicest looking clips of any folder I have seen. I like the round edges vs. many clips have square edges with sharp or rough corners. But, the clip is WAY too strong. I will "Quickly" tear up my pockets and about give myself a big wedgie trying to remove the knife from my pockets. I would prefer (REQUIRE) less tension for easier, smoother pocket attachment and deployment. Little details are important. I am actually pretty picky about most G10 folders on the market with rough G10 texture under the clip as the rough texture creates too much friction under the clip. In the T-Mag's case, I think the CF is sufficiently smooth, but the tension on the clip is MEGA powerful and is so strong that it creates way more friction with reasonably smooth CF scales than most reasonably tight clips on high friction G10 scales.
Also, for folders, I prefer less belly. I tend to use my folders for task chores and prefer a shallower belly. But, I consider that just my opinion. I really like the blade "edges" of the Mule, Caly3, Military & Para-Military and similar.
Factory Edge/sharpness: BEST ever! I have received a few VERY sharp Spydercos and some other notable sharp knives. I am pretty confident these two T-Mags have set the new standard for out of the box sharpness. I thought I was getting pretty darn good edges on some of my knives. I often improve most factory edges. But, I don't think I can improve these edges.
One other issue: the discription on the site for the T-Mag specifically states:
"The
flat-ground blade is laser cut CPMS30V....."
Mine is clearly "Hollow Ground". I thought I understood the difference between flat grind and hollow grind.

Am I missing something???
I always prefer flat grind on my folders. (*Although, I wouldn't mind some convex folders....)
For fixed blades, I generally prefer convex grind, but I am very often fine with flat grind. I don't really like hollow grind on fixed blades with the exception of a few daggers and dagger type fighting knives that I collect for aesthetics and not use.
As much as I find LOTS of great things about the T-Mag, I can't honestly say the T-Mag would rank well as a knife I want to "Use" and carry to "Use".
But, I am still very impressed with looks and quality.
One "FUN" side note: The T-Mag is the most "FUN" toy knife to play with. The magnet is not good IMO for holding the knife open for "USE". But, it has a GREAT "Feel" for opening release and closing for fun. I play with this knife a lot. I put one in my car and one by my desk and now constantly toy with it opening and closing it for fun. I habitually do this with certain good folders (I particularly like Ken Onion assisted blades and Axis locks for toying....

)... But, the T-Mag has become my favorite "Toy" knife..... very addictive to me...
