What tools should I get to sharpen these knives, please?

Hi all,

I have just got a Victorinox Grand Maitre and a Torijo DP. I also bought a Sharpal ceramic honing rod.

Is that enough, or should I also buy a steel honing rod, and a whetstone? I have a 6-year old Kiwi knife, which I did not have to sharpen it until after 5 years, with a 2-wheel sharpener. Can I use it for the Victorinox and the Torijo?

For the whetstone, which one do you reccommend, please? Or should I buy a diamond plate?

I intend to buy a King 1000/6000 for USD30, which I find quite expensive, given the Victorinox Grand Maitre only costed me $36. I don't want to spend, actually. Can I buy something cheap instead?

Do I need to buy anything else so that I can use the whetstone?

Thank you.

Expensive whetstone vs. Cheap diamond plates

Hi! Seeking some advice on chef knife sharpening on a budget. I know almost nothing about sharpening. Love cooking though. Recently I got an expensive japaneese knife as a gift and I want to keep it in good condition. On the other hand I have some dull cheaper knives that I need to sharpen ASAP. Im also planning to get one of those cheap Kiwi nakiri knives for daily usage without being too cautious about ruining it.

Now I have a friend who has an expensive set of whetstones that I could borrow but I would like to be able to maintain the knives myself at least up to a point. However, I really don’t feel like investing into an expensive set of whetstones myself yet. Ive read here on Reddit that there are some diamond plates on Aliexpress that are extremely cheap and work great. Would these diamond plates get the job done for the cheaper knives? Is it a good idea to use them on the expensive knife too or will I ruin it by doing so?

Thanks in advance for any advice!

How can I clean the "dirty" stones?

Sorry for the very basic question, I see that everyone here is a professional in sharpening, but I am just a beginner in this world.

I have a thin layer of metal on some of my sharpening stones after a few sharpening. By feel, these stones don't have the drag they had before.

How can they be cleaned?

I'll try to add a picture to the post, but I'm a newbie on reddit, not sure how I'll manage.

Need help in learning to deburr tip of knives

As title states, I'm having a hard time producing a sharp/properly deburred tip. I can keep an angle with the help of some angle guides (Wedgegek guides), and I'm able to produce a really sharp knife except for the tip. I'm keeping in mind to lift my knife accordingly, to keep the same angle, as I move up towards the tip and I'm being extra careful with the pressure I exert on the knife (especially as I'm deburring the tip ex. pressure=force/area) as I want to avoid rounding off the edge.

If any of you fine sharpeners could give me a helping tip I would appreciate it. My process for sharpening is apexing and deburring off a Shapton pro 320 and finishing off with a Kangaroo tail leather strop.

How far am I from hair whittling?

I been trying to sharpen my pocket knife to hair whittling. The knife is 8Cr13Mov steel. I am sharpening on a 325/1000grit diamond stone. I feel like I am very close to hair whittling every time. When I run a hair on to the knife, the hair is just keep clicking. Is like the knife is able to click into each segment of the hair fiber but unable to break through :( I feel like is very close. Any one have experience that they can share with me. Anything that can help would be highly appreciated

Shameless plug

Y’all probably know about u/scrungertart ‘s angle guide by now. I promised a review when I bought it, and here it is!

I have arthritis in my hands, and I’m so glad I purchased this. There are sort of similar angle guides out there (like the one made by Hapstone), but none of them are all-in-one like this AND easy to grip and hold (even when I get oil on it). The angle-setting screws are simple to manipulate and the built-in driver means I don’t need other tools on hand—just this and a stone. This guide accepts blades as small as 1/2” wide (3/8” is too small, I tested it) and I haven’t found a maximum yet—just reposition your stone and you’re good to go!

My 11 year old is interested in sharpening as well, and this helps him with his angles while he’s learning. He loves using it! He just finished up with his first knife and is pretty proud of himself. If you’re looking to give your hands a break while still using your stones, look no further. Great product.

The hair-whittling is getting better

I recently whittled my first hair, as some may have seen in my prior post. I’ve since sharpened several more knives with the method I was using and discovered while doing this one that the angle changes slightly on the worksharp when using my lapping film addons, and my sharpness went way up after correcting for this. I can now whittle hair much more effectively!

Rieci, Professional Fixed Angle Knife Sharpener - RC-001A

Hi everyone,

I recently purchased a Rieci Sharpener (Model: RC-001A) from AliExpress, and I'm having some second thoughts about my purchase... The sharpener doesn't seem to offer as many aftermarket or third-party attachments as the genuine version — the Work Sharp Precision Adjust. The Rieci is clearly a copy of the Work Sharp.

I'm curious if anyone here has experience with the RC-001A. Specifically:

— How does it perform in terms of sharpening quality and ease of use versus the Work Sharp?
— Are there any recommended modifications or accessories to improve its functionality?
— Any tips or trick worth mentioning?

I appreciate any insights or advice you can share.

Thanks in advance!

Is high limestone concentration in water bad for whetstones?

Hello, I live in a place with high concentration of limestone and other minerals in the water. I’d like to know, if this will cause issues with ceramic whetstones, so I can prepare to maybe having to replace them more often and such

'Work Sharp Benchtop precision / WSBCHPAJ' for mainly pocket knives

Hello lads,

got a bunch of victorinox and leathermans for years and regular use, now some of them got somewhat dull so I thought I give this thing a shot. If there are better options for 50-120€ I am happy to receive recommendations.
One of the knives is the arc with 'magnacut' steel, is it good as well with these machines? Also I got a very downbeaten serrated blade on the good ole rebar, probably need something additional on that one.

Many thanks & cheers!

12° Dalstrong Knife

Hi I recently received a Dalstrong carving knife as a gift. It didn’t come out of the box very sharp and has a 12° bevel on it. I’m not good enough to sharpen it by hand with either a steel or a stone, and I can’t seem to find any commercial sharpeners that have that degree of bevel. Any suggestions would be appreciated.

Thanks

Help choosing a finishing water stone

Hello all, I recently decided to go down the rabbit hole of sharpening. I’ve was a Boyscout so I’ve done some knife sharpening with a whetstone in the past but it has been many years. My wife has a lot of knives that need sharpening so I did some research and landed on the Naniwa Pro line Chocera for most of them. Below is the list of stones I have. My question is, for a finishing stone, what should I get? I’ve heard the Naniwa Pro 5k and above aren’t that great.

Naniwa S2 Advance - 220 Grit

Naniwa Pro Chocera - 400 Grit

Naniwa Pro Chocera - 800 Grit

Naniwa Pro Chocera - 3000 Grit

Does sharpening alter the grind?

I found that my knife wasn't very sharp ootb and was thinking of sharpening it, i noticed that a sharpened knife seemed to not be in that much demand, so i was wondering if it affects the grind or intended performance.

Beginner's equipment

https://preview.redd.it/wdtrjl1rnwge1.jpg?width=4000&format=pjpg&auto=webp&s=cdb822ce882d7c0f7a3d1b00585f3303b44512d1

I've recently started sharpening and this is what I've collected so far. The Coticule and bare leather strop is mostly for straight razor and the rest for cutlery. The set feels more or less complete, my edges are good enough and I should probably use it some more to decide what else I "need". So far I've been thinking about:

- a large Belgian Blue, which probably doesn't make much sense as what I really want is a larger Coticule, which is too big an investment atm

- a Naniwa Snow White 8k

- some Diamond-spray for the leather strop

- when the cheap Diamond is worn out, I'll upgrade to a Atoma 400

Many thanks for your suggestions.

Finally did it

Decently hair-whittling off an Atoma 400 and 1 micron rough leather. Knife is a tactile rockwall. The key was in pressure modulation. Even if the Atoma doesn’t cut under light pressure, I believe it will still burnish.

Quartz countertop

Got my knife very sharp with a Shapton pro 1000 grit. Thought I could do better but didn’t want to pay for a 3000 grit stone so I went by Home Depot and got a quartz countertop sample and holy smokes did a couple passes on the really improve my sharpness, absolutely blasted through the folded paper test like a laser beam.
