Review: Very impressed with my first Sencut - I had been eyeballing the Civivi Conspirator since I saw it in a Shot Show video a month before it was released. As soon as it was available I saw that Sencut (another company in the WE Knives/Civivi family) released 2 other knives that were very similar to the Conspirator the Mims and the Sache. Both had very similar features and were nearly half the cost. While I am trying to decide which of those I should get, they released this Serene and that is the one I finally chose. and this is why... 1. I think WE and Civivi make the best and most affordable button locks on the market and their Sencut button locks are just as good. Great lock up and perfect detent. If you deploy the knife using the thumb studs the blade rockets out and the button lock works great. I have even had no issues deploying using a reverse flick using the thumb studs. With some button locks you get a little bounce in the blade on the drop shut if you don't time it right, since this knife has a long blade the weight closes on the detent perfect every time. 2. The brilliant color of the aluminum anodizing is very cool. I got the blue and it is very vivid. it has a very nice satin finish but it's not so smooth It's slippery. It's similar to the finish on an Ultratech OTF. 3. It is much slimmer and lightweight compared to the other knives I was comparing it to. it is very thin but the handle is large enough to still be comfortable in hand. even the flipper tab is low profile considering the size of the blade but it still flips with authority. The other knives i mentioned are either G10 or Micarta which have a thicker profile. I rarely carry a knife this big anymore since I took an office job and am no longer in the field, so the fact that this is a big knife that carries like a smaller lighter knife is a big plus for me. 4.Blade geometry. The blade has a drop point style that reminds me of a Shirogorov with the full flat grind and distal taper of a Spyderco. The blade stock is fairly thin as well so it's a sharp and slicey blade that cuts through material with nearly zero drag. So for the first introduction to the Sencut Brand I am extremely happy with it. I love WE and Civivi, especially Civivi who in my opinion has been releasing the best quality budget blades in the last few years and I am always amazed what you can get from Civivi for such a low price. Sencut is definitely a chip off that block and I am interested in exploring more of their products in the future.
Review: Beautiful knife! - This is the perfect example of a quality knife that sells for much less than it should. As a big fan of WE and Civivi and I was excited to try out their newest sister company Sencut. And boy I am not disappointed I did! As usual with their brand of knives there is no blade play, the action is swift and enjoyable with ease of opening by both the thumb stud and the flipper tab. VERY SMOOTH! And with an achey thumb at times retracting the axis lock or frame lock on some knives just hurts after fidgeting with them over and over. So the button release is great for lots of fidget fun but with ease of retracting the blade. The detent is perfect and with the knife completely vertical as soon as I push the unlock button the blade drops smoothly all the way to the frame. No shaking or tilting l, just a nice controlled drop. I personally think button is quieter and smoother than my Claymore which when pressed feels a little grainy and has a little squeak to it. This is one hell of a knife for their budget blade cost. Will definitely purchase more Sencut knives.

### ⭐⭐⭐⭐⭐ Sharp and high quality.
*by T***H on June 5, 2025*

What a great product. Fidget factor is very high. The flipper tab works great, the button lock was smooth and easy to manipulate right out of the box. No blade play in any direction, solid lockup, razor sharp. Again, very very sharp from the factory. The fit and finish is fantastic. The aluminum scales have very smooth machined edges and it fits in my hand like a glove and feels very precise even for its size. The scales feel every bit as good as my 940 Osborne and actually to me a little better. It dissapears in my pocket and feels great in use. The black on black looks very good, like something John Wick would carry, very serious looking. For the price, I just dont know how you can get any better. This is my first Sencut and man what a way to introduce yourself. I will be buying more Sencut knives for certain. The quality, fit and finish are outstanding. I love this knife.
