My wife is absolutely a keeper, too. Couldn't live without her. One of the reasons?
Shortly after we were married, she asked me to borrow my knife. I told her "NO", and offered to buy her one of her own.
She accepted that at face value and that plan has worked for 26 years to our mutual satisfaction.
Background: I had a wife before the current one who borrowed my knife and promptly broke the tip of the blade off. Pretty much summarized our relationship.
The good news its a tool and it will wash. The other good news is you have now justified to her why you needed such a nice knife since you have not used it much. The next time you buy a knife you can always point out how great it will handle gardening task as a selling point.
Every gun is a gardening gun, if you do gardening correctly, no?
We were supposed to turn the soil in a gardening plot. I kept trying to explain how this could be done with much less effort, but for some reason my girlfriend just wouldn't go along with my excellent plan: first you grab a shotgun and some (probably preferably non-lead, like DDupleks Monolit) slugs, and shoot some holes into the soil. Next you grab some dynamite and cut the sticks into smaller pieces. Attach your fuse and drop a piece into each hole. Light your fuses when ready. Badabing, badaboom - the soil has now been turned.
(Don't forget to tune into That Guy's Gardening Programme again next week, when we'll be looking at the many uses of a flame thrower around the house and garden.)
Those Japanese Garden Knives are great. I've had one for over 20 years. It is the best small garden tool I own.
Pulling weeds, digging holes for planting, cutting roots with the serrated edge, cutting open fertilizer bags. A great tool.
