There's one here for £4.99! Surely it'll be the same quality as the £407 one!😁

My Uncle and his son were mechanics
They had tools that were used every day and lasted decades
a DIY person might use the same tools a few times a month if they are keen
the difference is massive from what I heard
My Uncle also kept a few older or cheaper spanners and the like around for "special purposes"
I saw that in action once when a nut on my Fiesta became rounded due to the use of cheap tools
he put an old cheap spanner on top of it and persuaded it to fit by the use of a large hammer!!!!
it did work - but we did need a new nut after!!!
The other problem is that manufacturers keep making things - especially on cars - that need a specific tool or a normal tools but with a handle a weird shape to get to the place it needs to me
so in order to be able to keep up to date they keep needing new tools
I have heard that they sometimes patent/copyright these - and when they drop out of protection other people start making them and if they are for a common car then garages buy them
it is all far more complicated than I thought - and is costing me a LOT due to a weird thing with my car that only a Honda garage can do as it needs a weird tool!
