Great work knife for the price.
I like this knife. It has a good blade shape to do work around the house or garage. The blade excels at cutting cardboard, cordage, opening packages, scraping things with the tip, trimming hoses..typical home stuff.After a couple days of breaking in, its smooth with a pretty good flipping action. Detent could be stronger but not a big deal.Fit and finish is nice considering the price but edges on mine were on the sharper end but 5 min of sandpaper and a file, its fine. The G10 scales are thin, so they do feel a little cheap but not crappy if that makes sense.If you're looking for a beater to use around the garage but still want something that doesn't feel crappy with a more "expensive" feeling action, this is worth a look, you might like it.

POOR CUSTOMER SERVICE, FAIR QUALITY BLADE
UPDATE: The clip on my rumble stretched out of shape, and I emailed Kizer, and sent numerous DMs to Tangram on Instagram, and got no reply. I was willing to pay for the extra clip and explained that in my messages, with that being said: I subtracted a star for poor customer service.The Rumble is a very good knife for the money. The knife is comfortable in hand, and the blade is very sharp and practical for daily use, and it has not failed me. My only compliant is that the G10 scales on the handles could be a little more aggressive. Additionally, I would like to see the Rumble in Blue, Orange, and carbon fiber.

Kizer hit a home run with this “budget” line of knives.
Hard to beat this knife for the money. The materials are great quality and the fit and finish reminds me more of a $100 knife. G10 handles are comfortable and the color is great. The steel is uncommon but it’s kept its edge pretty well. Resharpening was fairly easy as well. I feel it’s comparable to D2 steel, in those regards. The action is smooth and reliable and the large blade moves well. Lastly (and least important) I liked the box/packaging it came in. Small details that made the unboxing enjoyable. Kizer Knives has really hit a home run with this “budget” brand. I’d recommend adding at least one of Tangrams knives to anyone’s collection.The design reminds me of a Grimsmo Norseman that are custom made and retail well north of $1,000.

The poor man's norseman, but with flaws.
Loved the blade profile and the grind. Steel holds a shaving edge through cardboard and small firewood. Action is very drop-shutty with negligible (basically undetectable) blade play. Blade is perfectly centered. Good ergos and a great clip.However. the detent is VERY weak. Not unsafe... but almost unsafe. A weak wrist flick deploys the blade. It softens the blade action and can make deployment unreliable.Also, the flipper tab runs through a section of scales/liners with sharp, deep jimping. Flipping can be uncomfortable as a result. Bad design choice.

Heavy and tactical in appearance.
For the price a great workhorse of a knife. Comes sharp, great flipper action. Does take a little more time to sharpen, but for the money not a big deal.

Worst knife ever
My husband (who knows what he's doing with pocket knives) couldn't get the closing latch to work well. Either we got a defective one or it's just a terrible design. When he finally got the latch to unlock the knife (which took great force), he cut his finger really deep & needed stitches. Needless to say, this knife is pure trash.

Falls apart
Screw holding the blade together constantly coming loose from opening and closing.
