Ha-ha Old thread resurrected again
Will add my two cents. I prefer smaller knives and my comparison would be of small sebenza, 3" hinderer, and strider pt.
1) Price. Hinderer XM 3", is $385 from the maker (same as 3.5"), and currently goes for $550 or so. Small sebenza is $330 ($55 less than large one), and Strider PT is $300 ($100 less than SNG !!!). The later two can be found on secondary market for a lot less. So at the time of this post I could buy both strider PT and a small sebenza for the same amount as 3" hinderer. Taking this into consideration I would say that XM looses a lot of points here.
2) Quality. Hinderer and sebenza will top this category. They both have excellent very consistent fit and finish. As others have said with striders sometimes it is a Hit or Miss game. It is a shame that at the price asked for the knife quality control was pretty poor. I might be wrong, but I think that Strider improved their QC a lot, but there are still cases of not so good F&F.
3) Usability. Again as many have said most of the everyday tasks can be performed with a $10 knife and to me it is difficult to judge which of these three folders cuts better and by how much.
Sebenza is a tough folder, but for various reasons I would choose strider or hinderer for heavy duty tasks, maybe even for tasks not meant to be performed with a folder (I broke a 1/4" of the tip on my Spyderco, so I do know that such situations exist).
Sebenza has Ti scale that gets more noticeable scuffs opposed to G10 on strider or hinderer. Not really a big deal.
I like the clip on XM. Tip up or down, not too high, not too low.
In 3" format I would say all of them are sheeple friendly. I also would say PT has an advantage here, because in the most common hold you put your finger in the choil and hide the knife even more.
If wouldn't care about $$ amount, my vote would go to Hinderer, but at the current price it is not an obvious choice. Of the other two, I feel it is more about the personal preference than about anything else. I really like my small sebenza, but I prefer my strider PT.
