Graham/e, I'm not talking about the old profile JIS screws not being still available - I'm sure they are - I'm on about the tools that fit them.
Newer tools have been designed to work with JIS screws and with Phillips they are marked as say JIS PH3 - this change reflects the profile of new JIS tools on the market with the newer dual profiles so they work for both.(Clearly not all brands it seems)
I'm sure it has been mentioned on here that some new JIS bolts are sold without the dot mark on them this reflects the later JIS change in marking requirements.
You clearly inferred that my JIS PH3 screwdriver was not JIS standard - this is where I beg to differ - yes you might be able to obtain some JIS only screw drivers that are made in Japan to the old standard but certainly here in the UK all the tool retailers appear to be designating their JIS tools with the new JIS PH3 type specification reflecting dual use.

Old as you call them with a dot to identify as original JIS are very available. To test a JIS screw or a PH screw, just force blu tack on the head and remove to see the profile.
Here is a link to a picture that they are still available and i still buy them in bulk >>> https://www.ebay.co.uk/itm/166216111052?hash=item26b34093cc:g:huoAAOSwPGBd72zP&amdata=enc%3AAQAIAAAAwKjgbz9CoZUv4ghC8o4rtbcdn5Tyb%2FThQzovUGp6U9Xu21stnrrAa19WFgUcW%2FUThxZt2IVu1%2FFoKqmknFm6BPZQPBbPtAdRWeKt1QftmZ3gKl%2BFFiGuPNScgPlElHo5IJwz5vOAJ%2Bfp3b1BxoZPJshqUhAOM7u%2FIZGlYG1O0eK9GO75H9ZW%2FoOfnxImBQJVkcMrYdg%2Fe3AgglOEVtLwiTXagfp1FveuIHUrLB%2Bs4GbzS4DPxRkF8qcmSfKiO2HArg%3D%3D%7Ctkp%3ABk9SR4iTqcOpYg

Grahame the adding of the dot to the screw heads is no longer a requirement under the current JIS rules that cover manufacturing in a broad range of products. I suspect established manufacturers will keep the dot stamps until the machinery is replaced, newer firms have the option.
You are again missing the point I was discussing - the tool to use not screw head with or without a dot.🤔🤔🤔
Trigger:
I think you are missing the point JIS is JIS and PH is Phillips.
I sent a message to the manufacture were i get my JIS screws and bolts from and asked if they could supply me JIS PH3 head screws. They have never even heard of a mix JIS PH head and said, JIS is JIS and PH is Phillips as, they are a different shape ;)
McCabe-Thiele (Ted):
Yet again Graham/e you are talking about ordering JIS screws from your supplier.
I am talking about the Tools to fit those screws.
Like it or not it appears that an agreement has been reached involving Europe, the US & Japan to enable a single tool that can be marketed that will fit both types of profile - these are marked as for example a JIS PH3 screwdriver.
I have never suggested that a standard Phillips Screwdriver will fit into a JIS screw head they cam out I think is the expression.
I do maintain however that a tool marked as JIS PH3 will fit a JIS screw with no cam out and can be used on a Phillips head. The difficulty might be that the manufacturing process is very precise so not all brands work as they should. That was the conclusion in one of my earlier references.
On the subject of screws for a moment - below are two advertised JIS screw photos downloaded from e bay. The first shows the dot markings the second one does not - it so happens that the second advert is close to home you should recognise it.
