Read the tooth count and the maker's stated cut rate as separate specifications. If a rate is missing, leave it missing and ask. You cannot fill that field by turning the tooth count into a percentage.
This guide is for the stage after you have decided what role a toothed pair needs to play in your kit. If you are still comparing the names, start with thinning versus texturising scissors. Here, the job is to make a useful model-to-model comparison.
Build a five-field specification sheet
Start with the full maker and model code at the top. Include the size and handedness variant so the sheet cannot drift into describing a different pair.
| Field | Record this | Keep this question open |
|---|---|---|
| Tooth count | The count published for that model |
Does the figure match the variant you are buying? |
| Tooth pattern | The maker's description and an accurate photograph |
What details remain unclear in the image? |
| Blade arrangement | How the maker describes the toothed and opposing blades |
Is the orientation or handedness explained? |
| Stated cut rate | The exact figure, range or wording, with its source |
Does the maker explain its measurement conditions? |
| Intended application | The maker's stated role and your intended task |
What does your educator need to assess with you? |
Keep these fields separate even when a sales page puts them in one sentence. Add a source link and date to each row. A comparison should still make sense when you return to it after a busy Saturday.
A worked example from Joewell
Joewell's HXT model page lists the HXT-30 with 30 teeth and a cut ratio of 15%. It lists the HXT-40 with 40 teeth and a cut ratio of 35%. These are the manufacturer's published figures for two named models, checked on 8 October 2026.
| Maker and model | Published teeth | Published cut ratio | Evidence |
|---|---|---|---|
| Joewell HXT-30 | 30 |
15% |
Joewell HXT model page |
| Joewell HXT-40 | 40 |
35% |
Joewell HXT model page |
The comparison gives you two documented entries. It does not provide a formula for another model, a promise about your result, or confirmation that either model is currently available from this shop.
Notice the wording in the final column: published cut ratio. Keep the maker's terminology visible. Do not relabel it as a guaranteed percentage of the whole hairstyle removed in one pass.
A second family shows why the shortcut fails
Joewell’s HXG texturising records list 20 teeth and a 15–20% cut ratio for HXG-20, compared with 17 teeth and 25–30% for HXG-17. Here the model with fewer teeth has the higher published range. Together with the HXT example, this shows why a rule built from tooth count alone is a poor buying shortcut.
| Model | Published teeth | Published cut ratio |
|---|---|---|
| Joewell HXG-20 | 20 |
15–20% |
| Joewell HXG-17 | 17 |
25–30% |
These figures describe the maker’s named models, not current UK availability or a guaranteed share of a client’s hair removed. Keep the published range intact; do not average it into a more precise-looking number.
Put the Yasaka YS tooth choices, Ichiro 16T, Juntetsu Kenshi or Kai Wasabi chunker into separate model records when shopping. Leave an unpublished cut rate blank. If the opposing blades are unclear, use the single and double-sided comparison before completing that field.
Do not turn two examples into a rule
It is tempting to see the numbers above and decide that adding ten teeth must always add twenty percentage points. Nothing in that small comparison establishes such a rule.
Keep the example attached to its model names. When the next pair has 30 teeth, look for that pair's rate rather than copying the HXT-30 figure across. When it has a different tooth pattern, record that difference without inventing its effect.
The same discipline applies to product photographs. A picture helps identify visible construction. Counting the teeth in a thumbnail does not supply the missing performance data.
What the percentage still leaves to check
A published figure is useful information, but ask what the maker means by it. Does the source describe a test method or conditions? Is the figure a range or an approximate value? Is the same method used for the two models you are comparing?
If those details are absent, record “method not stated in this source”. Do not quietly add your own assumptions about section size, number of closures or the result on a particular client.
Your working choice also involves the task, fit and teaching or professional judgement behind the technique. A percentage on its own is not an instruction about where to cut, how often to close the blades or how to work on a particular texture.
Keep the geometry visible
An accurate macro photograph should show the actual teeth, their spacing and the opposing blade. Ideally, the model identity stays attached to the photograph so it cannot be confused with a similar pair.
Use a diagram to learn what to look for. Use a real photograph and the maker's record to assess the product. A generic drawing cannot verify a named model's tooth shape, count or finish.
If a listing mixes photographs from different variants, ask for clarification. Do the same if the description uses one model code while the image or packaging shows another. Resolve the identity before comparing its specifications.
Handle missing or conflicting data cleanly
Use three plain labels: confirmed, not published and conflicting. They tell you what to do next without making the sheet look more complete than it is.
When one source gives a range and another gives a single value, keep both with their dates and URLs. Ask the maker or supplier which record applies to the current variant. Do not average the figures or choose the one that sounds more appealing.
When a tooth pattern is visible but unnamed, describe only what you can observe and flag the label for clarification. When a cut rate is absent, leave it absent. An honest gap is useful; an invented number can send the whole comparison in the wrong direction.
Send a question that can be answered
Copy this into your enquiry: “For [maker, full model, size and hand], please confirm the tooth count, blade arrangement, tooth-pattern description and published cut rate. What source and measurement conditions apply? I intend to use it for [specific role] and would also like the current care and service instructions.”
If you are comparing two pairs, send both model codes in the same message. Ask the same questions of each. Keep the response with the sheet rather than relying on a remembered conversation.
Put the shortlist in front of the right person
Take the completed sheet to your tutor, educator or relevant experienced colleague. Explain the gap in your kit and show the pair you already use, if there is one. That gives the conversation a concrete starting point.
For an apprentice, a course requirement or tutor's specification should be checked before choosing an alternative on the strength of a higher or lower percentage. The aim is a suitable tool for the work you are learning, not the most impressive number.
Keep the care guide with the model information. Toothed construction does not remove the need to identify the applicable maintenance and service route.
Quick answers
Can I calculate cut rate from tooth count?
No reliable conversion has been established by the example in this guide. Use the exact maker's figure, or mark it as not published.
Does a lower percentage automatically mean the better pair?
No. It is a specification to interpret against the intended role. It is not a quality score.
What if the two brands use different labels?
Keep each maker's wording, find its definition and record any uncertainty. Do not force unlike figures into a single ranking.
The Kasho Design Master 30 Tooth model gives you another exact listing to put into the record. Keep its model code and tooth specification together; do not turn the tooth count into a calculated removal percentage.
Your next step
Compare two candidates from the thinning range or texturising range. Fill the five fields and ask about the gaps before deciding.
