    The times are interesting for the proportion on each stone, which stones do you use? I go 400,1k ,5k chosera and spend less time on the 1k than the 400 and less time on the 5k than the 1k. Is you're 1k a particularly fast stone?

    I'd say I use about 12-15 mins on average on kitchen knives.
    The grunt of the work is done on the lower grits, but I can sometimes get completely hung up on finishing a single bevel properly, and then time sure flies

    Depends on whether or not I'm using a course stone that day or not but between 10 and 20 minutes is about the average for me. If I'm doing a full work up on the whole kit it can run into an hour depending on if I'm really really really OCD that day

    I've often said that if you're getting sharpening done fast then you're shorting out on something. Probably either sharpening at too obtuse of an angle or deburring is being skimped on.

    That said, I'm pretty fast and I don't skimp so sometimes it's less than 15 mins (rare) and other times (fortunately not often) it's 3/4 of a work day. If we're talking factory edges on new knives then it's obviously on the lower end, it's the repairs that blow times out of the water.

    Are we including thinning in this? If so it's well over 8 minutes for me, probably closer to 20. If I'm just putting a new edge on a knife without thinning it takes maybe 10 minutes.

    If I neglect thinning for a long time it could be awhile. Maybe 30-40 minutes, but I'm careful with thinning. I still use sandpaper to repolish knives, not stones, so that can be time consuming as well.

    Not thinning/repairs, or minor touchups. Just cut in a new bevel on a dull knife and sharpen it.

    Yeah, I was using a Shapton Pro 1k. The progression this time was Atoma 140, Shapton Pro 1k, Suehiro Rika, Sigma Select II 10k, and a leather strop with 1 micron diamond spray. I think I spend so much time on the Rika just because I like it. I threw off the averages because I zoned out on like three knives, just sort of lost in thought and hypnotized. I ended up spending like 5 minutes on a few of them. The times include deburring, because deburring on the 140 and 1k took 30 seconds and 20 seconds on average, respectively.

    Longest times I've spent sharpening a knife that didn't require refurbishment:
    I remember doing that Monosteel giveaway knife(whatever it was) and that thing took me most of an afternoon. Also, Brad Stallsmith's CPM 154 on an old run of Addicts took 6 hours for 5 of them, but I was being really cautious back then, and trying to re-set the bevels on a 1,000 grit stone.

    I did a major refurb today. I ordered a Tojiro 210 ITK Gyuto for a friend's upcoming birthday. While I was looking it over I dropped it. 5mm off the tip and a 1.5mm chip on the blade an inch below that. I didn't bother stewing so first thing this morning I ordered her a fresh one. Then I put my stones in to soak, went to my shop, sharpied the least amount of removal and put it to my variable speed grinder. Cleaned the profile up with 180 sand paper on my jointer bed then put it to the stones. 500, 1k, 6k then strops - I also started thinning the blade and ended up with a super nice edge. Total time probably hour and a half start to finish. Looks like I'm keeping "shorty" for a while as it cuts really nice now. I might use it for a first re-handle project then give it to another friend. I love these knives for the price point they are hard to beat.

    While the stones were wet I put a fresh edge on my Lamson Chinese cleaver - I forgot what a nice knife it is when it's sharp -

    I seem to get alot of Shuns they have a good distribution network out here.Just sharpened a girls 10" Shun Premier,very dull.Start wt. 600 Atoma careful not to scratch the Damascus wt. my back bevel.remove burr,polish out backbevel wt.1200 bester,deburr,polish out backbevel again wt.5K Rika.(polishing the backbevel each step creates less drag cutting food)Raise the spine & cut in final bevel on the Rika,you can hear the bevel being cut in on the polishing stone.deburr.Because no damage to repair my guess is about 10 minutes tho I never time myself,could be longer.

    Dull stainless knives I like to start wt. Atoma 140,it's also good for repair.I got the 140 first,liked it so much bought the 600,since then my low grit stones collecting dust.1000 up I like the stones.

    synthetics are generally faster cutting... especially on the coarse side and especially with stainless and pm steels
