About Motokyuuichi Hamono 本久一刃物

From the historic town of Shimabara, Motokyuuichi Hamono (本久一刃物) builds on a blade-making legacy stretching back to 1895. Inheriting the knowledge of esteemed swordsmiths, the Maeda family transitioned the craft to create exceptional kitchen knives. Today, the lineage is proudly continued by the father-and-son team of Kiyonori Maeda, the 4th generation master, and his son Yasuhide, the 5th generation. Central to their cherished method is the use of Shimabara’s pristine, volcanic-filtered water in the quenching process. They consider this unique water essential to their craft, allowing them to forge blades with their signature resilience and sharpness. Each knife embodies this multi-generational story, blending ancestral wisdom with the passion of its current masters.

About Hatsukokoro 初心

The Hatsukokoro brand, also known as "Shoshin", collaborates with a variety of artisans, from blacksmiths to handle makers, to ensure that every aspect of the knife gives the best quality to price ratio. Every knife is well curated, with makers and materials chosen specifically to suit the intended line. Based in Amagasaki near Osaka City, Hatsukokoro partners with workshops and blacksmiths from across Japan, resulting in a diverse range of knives that cater to all budgets and preferences.

Care:

Aogami Super (Blue Super) steel is considered the most superior Japanese high carbon steel for knife making. Despite some corrosion resistant quality (for a carbon steel), it is not stainless, therefore you should wipe your knife dry after each use. Patina will develop over time. Rust may develop if left in prolonged contact with water or acidic food. Use a rust eraser to clean if rusts develop. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.

Expansion band proved a disappointment
Size: 25mm, Color: Two-Tone/Two-Tone/White/25mm
I shopped many watches before I decided on this Timex model. I've been wearing Timex watches for the last several years and have found them to be reliable and reasonably priced, so I was pretty much set on buying a Timex. I have one of their Weekender models with a couple of different straps, which I alternate depending on what I'm wearing, and I really like it. I also had a dressy model with the same easy-to-read dial that had an expansion band, and it died on me after several years, so I bought this watch as a replacement. The watch works fine, and I like the easy-to-read dial and also the fact that it has the Indiglo light. Plus, the watch is attractive. I was disappointed, however, in the band. The expansion band on my old watch fit perfectly, and the edges of the band were nicely rounded and smooth so that it was very easy and comfortable to put on and take off. However, the band on this new watch seems a little bit smaller, so it tends to pinch a bit. Also, the edges are sharper, which makes the watch rather uncomfortable to put on and remove. This was a let down. I don't know if these differences are due to a decline in quality control, an effort to reduce costs, or what. I considered returning the watch and buying a different model, but since there wasn't actually anything wrong with the watch, I knew I'd have to pay return shipping, and I didn't want to invest that extra money. So I kept the watch. But I'm not entirely happy with it, solely because of the band. Of course, that's the problem with shopping online--you can't try it on before you buy. If you have a thin wrist, this band may be fine for you, but if you have an average or larger wrist, you may likewise be dissatisfied.

I’m so pleased with my Timex watch. I can actually see the numbers and the added feature of the lighted face is great.

Perfect for Training (Swimming) Purposes.... 5 Star for what it does as a training watch!
Color: Black/Yellow
This is already my 2nd TIMEX which I use for my swimming practices.. This one beats the older model (Timex 51931 Ironman Triathlon) with some interesting changes: 1) The larger digits on this model makes it easier to read the numbers (as some mentioned to do so when running) even when I am swimming, with a quick flick of the wrist at the turn, it's possible to see the minutes and the seconds.... The older model had smaller number, thus not making it possible to do this. 2) The navigation on this model became quite easier. It was already easy on the older model but this one included instructions on screen, such as NEXT, DONE, + or - in order to advance with your practices and training... Plus a chance to change the way you want to see the information of the your laps (Laps in the big digits and splits at the smaller one, or the oposite) A Real nice add on by TIMEX. 3) A simple but effective wrist band "clip" (the tiny piece of strap that attachs the "extra" wrist band that is left after you put the clock on) It has a piece of rubber on the inside that locks on at the wrist band and does not make it loose or even letting it go as some other watches do sometimes. This is more effective underwater I think, as it remains the way you set your wrist, as the older model I had did not quite held in place all the time. 4) Plenty of memory (100 laps is really a nice number), maybe more then most will need but, as a swimmer I use to count splits over 100m (or yards) with many laps during one training... It is quite usefull. I go easily on 10 to 15 laps of the memory in one training. And with the date feature, that reminds when you did these times, it is quite usefull to keep track on the training with a spreadsheet, for instance... (as I do !) 5) A really big START/SPLIT buttom that is great to press when I am swimming laps and have to press myself at each turn at the pool. Just perfect. Never a miss ! And the feature which was already at most of the models, of the repeat countdown, and the start of a chrono, or a repeat (what I use the most) in order race agains your average rhitym inside a certain time frame that you can set it up ! And of course the flix technology, which is very good to have it... Just flick your wrist (when you set it to ON) and it will show you at night all info that you need. It is another great watch from TIMEX and it deserves a look, specially for the price. It is worth to pay a bit more if you are like me and uses a lot of the memory for the laps on swimming pool. Maybe for runners it can be quite a lot of memory, but the price difference is worth the change, for some of the options mentioned at this review. This is a really good watch to have.. Will you definatelly like as we all are at these reviews. :-) It deserves the 5 stars rating !

Great sports watch.
Color: Black/Yellow
I have to admit to being a bit of a watch fiend, having one for almost everything I do, but this is one of the most useful, yet cheaper priced items I've come to enjoy. When I work out I like as much information as I can get, so for running and biking I have a watch for that, but for swimming I needed a watch to help me count my laps and log my times. The Timex Ironman 100-lap watch does this quite well. I first got a Timex 50-Lap watch that I was able to find locally, but 50 laps is very limiting so when I found this watch for less money and a bigger face that had the lap/split time and lap number on the screen at all times I knew I had a great product. When you're finished with your laps just save your workout. The watch will then calculate some information like average lap time and best lap. I haven't completely messed with their data, but I think they average your times by throwing out the lap times that are the outliers, which is good for the accidental laps where you hit the wrong button, but it's not as great when you did a few sprint laps and they don't show up as your best time. If your best time isn't on there you can still recall it by going through each lap individually, but I think my sprint laps sometimes aren't listed as my best laps. I haven't messed with this feature much because it isn't important to me, and removing the outliers is good for looking at your actual pace. I have been able to push myself a bit more in the pool by having actual numbers to compare, which is very helpful. The other features on this watch I haven't used much, but for someone who can't afford a GPS watch and can use maps or a track this watch would be great for running or anything with laps or intervals. It has up to 9 interval timers and once finished it can either stop or repeat the sequence. It can do what's called chrono at the end, where it just switches to the chronograph feature after your timer or interval timers are finished. Overall this is a great watch and for most people who enjoy doing anything with laps look no further.
