  1. Blade play Review by
    A little bit of vertical blade play when opened. The rest is perfect. (Posted on )
  2. PerfectReview by
    A perfect folding utility knife based on the original Sardinian design. Very simple, sleek and superb quality. Can be opened with one hand with a little practice. This is a fairly large knife, but slim enough and light enough to keep in your pocket without feeling awkward.
    Lock up is precise with zero blade play. My first experience with N690C steel and I'm really impressed with it. Supposedly similar to VG10, it holds a good edge and sharpens easily. Razor sharp.
    The blade is long enough to be suitable for food prep ,and with its sharp point, also suitable for any finer work.
    Quality comparable to any high end folding knife.
    Very pleased with this, and has been in use every day since purchasing. Recommended.

  3. Pointy sharp!Review by
    This is a really well put together, high quality blade. A real slicer, giving you everything that you could need in a knife. I've not skinned anything yet, but the blade shape makes it very controllable. If sliced chicken, beef and vegetables with equal ease. The blade is perfecto centred with clean grinds and its SHARP!

    I also really like that there isn't a pocket clip.

    Great addition to any collection.

  4. A lovely thingReview by
    A very pretty knife and my favourite ER "basic folder", taking its inspiration from older more graceful designs.
    The Resolva is sharp, pointy and smooth with a perfect lockup. Also probably the cheapest way to include a high quality ER folder in your collection OR equip yourself with a nice folder for regular use.

Questions & Answers

Have never owned anything from Extrema Ratio. How does the quality compare to Spyderco, particularly with the Resolza/ Pattada.
I am a little bias as I own a Kukri and have for several years, the fit and finish are superb and the simple clean lines are a excellent design and really is a thing of beauty. Quality is equal to Spydercos high end knives :) Extrema are a premium product.
