A sharp chisel pares wood cleanly; a dull one tears and slips. Most tutorials rush past the geometry that matters: the relationship between primary and secondary bevels determines how quickly an edge degrades, and the state of the flat back determines whether honing will work at all. There is also a gap between initialising a new chisel and restoring one that is genuinely knackered, two different tasks that rarely share a video.
Short verdict
Start with Matt Estlea's full walkthrough if you want to understand what you are doing and why. Confidence comes with repetition. Once the method is in your hands, Paul Sellers' two-and-a-half-minute clip shows what routine maintenance actually looks like. For anyone who has only a piece of glass and some wet-and-dry paper, The Wood Whisperer's short is a genuine working method, not a second-best option.

How To Sharpen a Chisel (The Correct Method)
Matt Estlea · 26:37 · Dec 2021
Matt Estlea's 26-minute guide opens with chisel geometry — what the primary bevel angle (around 25°) and secondary bevel (around 30°) are for, and why getting them right determines how long an edge holds 1:39. Chapter markers let you jump to grinding 6:42, hollow-versus-flat grind comparison 15:20, honing guide setup 16:05, or stropping 22:15 without re-watching the whole thing.
Why it ranks here: It earns the top spot by explaining why each step exists, not just the sequence. The frank treatment of honing guides versus freehand 16:05 cuts through the debate that fills comment sections elsewhere without dismissing either approach. A real-time demo at the end 24:49 shows the full sequence without cuts, so you can see how long each stage actually takes. A commenter notes returning to it 'as a refresher for the various stages in sharpening'; another calls it 'the most comprehensive instruction I've seen on sharpening.'

How to Sharpen a Chisel | Paul Sellers
Paul Sellers · 7:13 · Feb 2017
Paul Sellers works through a brand-new set, demonstrating that factory-ground chisels are typically finished only to around 150–200 grit 0:34 and not truly sharp. He flattens the back on diamond stones, notes explicitly that a hollow back does not need removing 1:47, sharpens the bevel freehand by feel 4:01, and finishes on a strop charged with buffing compound on a block of wood 3:00.
Why it ranks here: This is the natural first video for someone who has just bought their first chisels. It is the only video in this pack with a human-generated transcript, meaning every word is confirmed. Sellers' advice not to obsess over full-back flatness 1:07 saves beginners from spending an afternoon on an unnecessary step, and his strop-on-a-block technique 3:00 requires nothing beyond abrasive compound. A commenter reports going from 'never sharpening my chisels because I had no idea how to' to getting all their old and new tools into good working condition directly from this video.

Sharpening a Chisel in under a Minute | Paul Sellers
Paul Sellers · 2:40 · Jun 2023
Sellers takes a chisel that has been in use for an hour — shiny on the bevel but no longer cutting cleanly — and works through coarse, medium, and superfine diamond plates before stropping thirty pulls bevel-down 1:20–1:36, then a few pulls flat-side down to break the burr. The whole process is shown in real time with no cuts.
Why it ranks here: This is the video to watch once you have the basics and want to know what upkeep looks like mid-session. The 58-year freehand technique makes a quiet case that a honing guide is optional for maintenance sharpening. A commenter puts it plainly: 'After a few years of using a honing guide, I started sharpening freehand. By removing the setup time... I find myself sharpening faster AND more frequently.' The under-three-minute format means you can watch it again while your strop dries.

Sharpen a Chisel | Fast & CHEAP! #shorts
The Wood Whisperer · 1:00 · Aug 2021
The Wood Whisperer tapes 320- and 1,000-grit wet-and-dry paper to a flat piece of glass and uses water as a lubricant — no stones, no specialist tools. He flattens the back starting on 320 grit 0:10, works just the first inch or so 0:22, moves to 1,000 grit 0:26, then works the bevel with an optional micro-bevel at the tip 0:41, stopping when a burr forms on the back 0:43.
Why it ranks here: The glass-and-sandpaper system is the lowest-barrier method in this pack. It needs no specialist outlay. A commenter confirms using it on chisels and knives with results that are 'hard to argue with.' The one practical caveat comes not from the presenter but from the comments: smaller glass panels are often not truly flat, which defeats the whole method — a thicker piece of float glass is more reliable than a small picture-frame sheet.

Sharpening a Dull Chisel - Ask Matt #8
Matthew Cremona · 14:06 · Feb 2015
Matthew Cremona deliberately destroys a chisel — prying paint tins, dropping it — then restores it from scratch. He begins on a slow-speed wet grinder to re-establish the primary bevel 2:49, uses a honing guide with a setup gauge for consistent protrusion 5:08, works through waterstones up to 8,000 grit, and flattens his waterstone with a diamond plate when it becomes hollow 9:00.
Why it ranks here: This is the only video in this pack that starts from a genuinely wrecked edge rather than a lightly dull one. The Sharpie-on-the-bevel trick 6:15 — marking the bevel with a felt-tip to see exactly where the stone is making contact — is a practical diagnostic step the shorter videos skip entirely. Cremona also keeps a visible bead of water on the wheel and pulls the tool back the moment it starts to steam 4:26, a heat-management habit that matters on any bench grinder.

Where the videos disagree
Should you use a honing guide or sharpen freehand?
Matt Estlea recommends a honing guide for angle consistency, particularly for beginners, and demonstrates the full setup [16:05 in ip_MHACrqKs]. Matthew Cremona also uses one with a protrusion gauge. Paul Sellers sharpens entirely freehand in both his videos, finding the bevel angle by feel, and makes no allowance for a guide in either.
Our read: A guide removes one variable when you are learning and makes the secondary bevel reproducible session to session. Freehand is faster once the muscle memory is there, which lowers the threshold for sharpening frequently. Both positions are honest — the disagreement is about stage of skill, not which method is objectively correct.
How flat does the back need to be, and how far back must you work?
Paul Sellers explicitly advises against obsessing over full flatness [1:07–1:14 in GN4yr7vp4I4], saying you need a flat reference only at the cutting edge. Matt Estlea and Matthew Cremona both treat a properly flat back as essential preparation and work the first inch thoroughly. The Lie-Nielsen presentation goes further, arguing that the full back matters for chisels used in paring.
Our read: For general carpentry and chopping work, Sellers is right — the first inch near the edge is what does the cutting. For precision paring, where the flat back rides against a shoulder or a scribed line, the more rigorous position applies.
