Amazon Prime Day tool deals I used as a full time bike mechanic

Pedro's socket II: £23.05 £15.99 at Amazon
31% off - A socket tool to remove a bottom bracket is a far nicer experience than using a spanner. The Pedro's II is probably my favourite ever. It's solid and a good weight, accepts 3/8" drive tools or a big adjustable spanner and fits all 16 notch / 44mm bb cups - that's the larger size Shimano HT2 fitment.  There's also a lifetime warranty. 

Draper Engineers Scriber: £10.62 £7.75 at Amazon
27% off - I used an engineer scriber or simply put 'a pokey stick' every day when running a workshop. They are incredibly useful for a wide range of jobs. Opening up brake or gear housings, removing dirt and mud, marking cut points on steerer tubes, the list goes on. Invest in one and you'll be surprised how much it can do.

Park Tool Big Blue Book: £27.99 £20.99 at Amazon
25% off - The Park Tool Big Blue book of bicycle repair is up to its 4th edition now and is an excellent resource to have at home. It's packed full of information, torque spec charts and much more. And you'll have it on your shelf to reference forever.

Thor 710 Nylon Hammer: £17.53 £13.50 at Amazon
23% off - Modern bike parts are delicate and need a deft touch sometimes when servicing them. This Thor nylon hammer was my go-to when servicing wheel hubs, where a heavier-weight metal hammer was overkill. The 710 from Thor won't damage lightweight components when you still need to use some force.

YUNGMAX Brush Set: £5.99 £4.79 on Amazon
20% off - This is officially a bottle-cleaning brush set and you can obviously use the large one for cleaning your cycling bottles. However the smaller brushes are very useful for cleaning dirt out of hard-to-reach places, my main use was scrubbing the inside of brake calipers and getting them super clean and free of contamination, essential for top-performing brakes.  

Rechabite Magnetic Pickup Tool: $6.39 $5.59 at Amazon
13% off -  This handy telescopic magnet proved very handy on a daily basis, whether it was helping to route cables, retrieve debris, or trap bearings when servicing hubs. For the money, it's a handy tool to have in your toolbox.

Unior Hub Genie: $41.40 $32.25 at Amazon
22% off - The Unior Hub Genie is a really useful tool that helps cleanly remove thru-axle end caps which sometimes can be really tight. If you're servicing your hubs or swapping axles, this is a real-time saver. The 12-15mm size tool is discounted.

MulWark Mini Ratchet: $16.98 $11.51 at Amazon
32% off - A tiny ratchet like this got me out of trouble on numerous occasions. The 90-degree angle of the head means it can exert a lot more torque than a screwdriver for example and I had a lot of luck with it when removing seizing Shimano brake caliper pins. 

YUNGMAX Brush Set: $7.99 $5.27 on Amazon
34% off - This is officially a bottle-cleaning brush set and you can obviously use the large one for cleaning your cycling bottles. However the smaller brushes are very useful for cleaning dirt out of hard-to-reach places, my main use was scrubbing the inside of brake calipers and getting them super clean and free of contamination essential for top-performing brakes.
