I have to say I always used the stick but this rock, ROCKS!!!!
I was just walking around Old Town San Diego and I found this little Japanese store with swords and I went inside, really cool place with a nice lady that works there.
I was about to leave the store when my husband said, “why don’t you try this sharpening rock for your knives” and I saw the price tag $2 and I said, SOLD!!!!
Listen, This thing is amazing, you need to let water run over your knife and the rock when you are sharpening but This things works way better than anything out there.
There are tons of videos on YouTube showing the proper way to use this rock if you are in doubt.
Give it a try, its cheap and does its job.
