My tuppence FWIW: chip-breaker problems are more often caused by twist than by hogging or sagging [apologies for the naval terminology]. Screw on the CB, and check WHERE the gaps are. If they're symmetrical side-to side, that's hogging or sagging. If towards one side, that's twist. Cutting irons can also come twisted, but more rarely. To remove twist, it's between 'very helpful' and 'absolutely necessary' to have a flat diamond stone at leat 8" / 200mm long. Put the CB face down; put most of the pressure on the area around the screw-hole; skim off the twist from the front lip. Once the twist is out, turn it sideways, with the body below stone level, to relieve the back of the front lip, and allow the front edge to bite onto the cutting iron right across. CXjheck carefully, looking straight at the clamped-up cutting and CB irons. The SLIGHTEST gap will seriously degrade performance, and cause the plane to jam up.

I can now confirm that Hock blades and cap irons are very good and I can get thinner shavings, all else on the plane being equal. I have sharpened them only when I unpacked them and I did not notice that sharpening would take any longer than on the standard stock blade. But I will see after I dull the edge, as the factory edge was pretty sharp so not a lot of material was taken away.

The only think that I did not like was that they glued sharpening instruction to the blade and I had to scrape away 8 glue dots on both blade and cap iron and then use a solvent to get rid of the glue marks completely. If they just had the instructions loosely in the package, nothing bad would happen.

the bevel down ones don't have cap irons Ttrees, they have an adjustable mouth instead.
???? Have you confused your ups & downs tyreman?

Cap-irons are only used on "bevel down" plane blades - they would serve no purpose on a BU blade other than to stiffen it, but that's more simply achieved by having a thick blade.
