### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Absolutely amazing!
  

*by C***T on Reviewed in the United States on June 21, 2009*

I bought this with the hope that it would actually sharpen my garden tools (pruner, lopper, etc) rather than just make them a bit less dull than other sharpeners I've tried. Absolutely amazing! It restored a 10 year old pair of pruners to sharper-than-new condition! I then tried it on a pair of loppers where the blade was folded over where I accidentally hit some wire. Filed off the damaged part with the diamond paddle side, then sharpened it with the convex side. Again, better than it was when it was brand new!Istor makes three models of this sharpener. They all work the same - the differences are in size and whether it has a file. The base model is fairly small, but also quite inexpensive. Good choice if you have small hands. The middle model (I think they call it the Professional) is a bit larger, and more comfortable to use. The sharpening end is also a bit larger than the base model. This model, the Duplex, adds a diamond coated file (the flat paddle side) which is perfect for re-grinding blades that have been damaged or nicked. Very easy to use -- just draw it across the blade.I think this model is the best one for gardeners, since it's not uncommon to nick or damage a blade, and the file will let you grind out the damage before putting an edge on. If you're looking to sharpen mainly knives and scissors, either of the other two models will work well at a lower cost.If you want a sharp edge, get this!!

    does the job, once you figure it out
  

*by J***L on Reviewed in the United States on September 1, 2011*

This item comes with no instructions and it is NOT self explanitory. I made my best guess and got the job done, but so far as I know, I may be ruining the sharpener.

Have used this to sharpen all of my pruning shears and pocket knives.  Its has worked very well.  Although it is a bit pricey, it does a good job and I am pleased.
