Introduction - What Is This Woodworking Tool From 1761 Called?

Introduction
Hi again!
Now, yesterdays post was a bit of a test to see how everything was working.
Well, now that I have some of the basics figured out, I thought I could introduce myself properly.
I'm 23 years old, live in Norway and have a full time job as a costumer care agent.
Because I mainly sit still for 40 hours a week, I need some way to release some steam in the weekends.
I found that a few hobbies would help me out in that sense.
Some of those hobbies are fishing, woodworking, gardening, drawing, knives, axes and restoring antique tools.

Fishing
I grew up far from civilisation, without cell phone reception, practically without neighbours, so with me and a fishing rod in hand and the sea just outside my window, that's where I feel I belong the most.

Gardening
Fishing is something I would to more often, but since the house pictured above is our vacation home, the home I grew up in, I'm not there very often.
Therfore I turned over to gardening! Growing a few plants here and there, keeps my mind off work, and having a little bit of green in the livingroom windows during winter keeps the whole house sane.
I found out the hard way that gardening in Norway was a bit more tricky than other places. We can't plant anything outside before middle of May, and all the plants are dead and gone in the middle of october.
Because we live close to the sea still, salt in the ground and the air is yet another challenge.
The sunrise and sunset is also a bit of a problem. Take today for instance. The sun rises at 3.16AM and sets at 11PM.
Plants need e bit of rest in the dark to recover, as we do, so vegetables that are not native to this area have a hard time surviving just because we don't have enough darkness in the summertime.
A simple setup with a few raised garden beds, good soil and enough organic matter helps the plants last into July when the nights gets darker.

Woodworking And Tools
The most recent hobby I've aquired is woodworking and antique tools. Restoring the old and bringing it all back to life.
It's a wonderful experience to to aquire a old, neglected tool, grapping a bit of sandpaper and oil, and then giving it new life.
I won't go much into detail on this theme, but I thought I could show you all a picture of the oldest tool that I've found digging through scraps and junk in the barn I mentioned yesterday!
If anyone can give me the english word for this tool, I would much appreciate it!
It is carved "1761" on the handle, and the makers mark is on the other side!
A true relic from the past.

Thank you again for reading!
Writing is not my strongest side at all, but at least I hope you will find the pictures interesting!
