Tools you wish you’d bought sooner

So, following a similar thread on another forum I use, I thought this may work well on here.

What are the tools you have bought that you wish you’d had years ago? Really useful to share recommendations and see what I’ve been missing!
Mine is a very simple one, the edging knife. I’ve always worked with a spade, never getting a properly straight edge or cutting through turf as easily as I should. It’s a revelation now I have it!

I dug a border last year and had to take out football sized lumps of old tarmac, only hand tools that made sense.
I quite like my hand stump splitter as well though.
My best one is a bit narrower but i have a couple. You can slice weeds like geum urbanum off , slice pulmonaria ( which will regrow if you want it to) scrape weeds off the path, edge your grass , hoe in between plants. Best hoe I ever had
Mattock is number 2
East facing, top of a hill clay-loam, cultivated for centuries (7 years by me). Birmingham
That, plus a quality bulb planter. I used to stubbornly dig bulb holes by hand, then got a planter and realized the time saving and ease.
