Been dropping in on this thread for a while and finally thought I would chime in…
I’ve had a full set of Henckels 4 Star that I purchased in Germany 30y ago. I tried manually sharpening with the lansky system and rods until I got a chef's choice 130. The problem with them is that the bolster that extended all the way the the knife edge caused me grief - even with the manual methods.
I tried my brothers Shun (VG10) about 10y ago and finally got myself a Myabi Artisan 8” chefs knife (SG2) - wow! I have been replacing my henckels piece by piece as I run across them on clearance - first at zwilling.com and now at cutleryandmore.com
Here is what I’ve found at zwilling - they have great clearance deals on visually imperfect items (especially at Black Friday). I bought an Artisan 9” bread slicer with an end cap that is not embossed evenly across the surface for $99 - I especially like the extra hard SG2 that will hold serrations extra long without needing sharpening because, well, I can’t sharpen serrations easily at home. I also got 2 clearance paring knives from their VG10 lines ($39 each) and I can’t find any imperfections - except each has a dot in exactly the same place on each blade. I think they purposely added these marks and sold their overstock at clearance prices.
Cutlery and More has sales and clearance of visually imperfect knives (again check Black Friday) but also has their own exclusive lines Yaxell and Enso, and their Mizu by Miyabi (Artisan with different handle). I got an Enso Ketu 6.5” Santoku SG2 on clearance for $99 (exact same blade design as Miyabi Artisan)
On a trip to Japan last year I thought I’d get a knife as a souvenir and dropped by several small family run knife shops and noticed something about them. They all finished the knives in the store - final shaping of blade and handle, sharpening, polishing and would engrave whatever kanji you wanted - but the knives were all very similar in metallurgy, Damascus layering, hammering, etc. it became very obvious that these little guys were buying nearly finished knives from a handful of manufacturers and putting their own ‘artisanal’ touches on them for ‘authenticity’. And none of the knives could touch the prices I could get from zwilling or cutleryandmore when on clearance
So here’s where I’ll “Weave” it all together (my opinions only)
20deg sharpening is legacy and meant to hold that sharpness for longer since sharpening used to be much more difficult and inconvenient
You can take any blade to 15deg and now, with electric sharpeners and services, maintain even your soft steels on a regular basis - henckels and wusthof now ship with 15deg
The 9-12deg advertised by Japanese mfrs is because they rely on hand sharpening to finish blades and “it sounds artisanal”
VG10 clad knives are probably the best for cost/performance/durability
SG2 clad is generally not worth the extra $ over VG10 except maybe for specialty knives that are difficult to sharpen (serrated or extreme curves)
Electric sharpeners satisfy my 80-20 mantra - 80% of performance with 20% of effort
Cooks illustrated has recommended the victorinox/forschner 8” chefs knife for as long as I can remember- very sharp, cheap and can be sharpened/maintained easily because no bolster
I’ll end with: Sharpness is subjective and you can manually sharpen at 15deg better than chefschoice at 15deg, but it’ll take much longer and require much more experience and skill
Also Cutlery and More has their exclusive 14deg chefs choice sharpener at $139 with another 20% off coupon available right now =P
This Chef's Choice Electric Knife Sharpener sharpens to a razor sharp 14 degree edge, double bevel, and is ideal for all knives especially Wusthof. Chef's Choice Sharpeners are made in USA.
