Review: Nice little roll for pens and pencils - Absolutely love this for my art supplies. It doesn’t hold a lot but that is exactly why I purchased it. It holds the perfect amount, half a dozen pencils and microns. It's not too bulky, easy to access and gorgeous leather! I purchased the green, doesn't truly have an olive green color, leans more brown, which was disappointing because green is my favorite color. Nevertheless, I am keeping it and am glad to have it as part of my art supplies for nature journaling.
Review: Best Snap Off Blade Knife By Far - I use this knife, which uses 1" wide break off blades, as part of my work as a contractor. I have tried at least 6 or 8 different snap off blade knifes in the past and this one is by far the best of them all. The blade is really sturdy and does not break off easily. The metal sheath that holds the blade keeps it straight and does not allow the blade to wobble around. The black knob that tightens down to hold the blade in position is easy to adjust with just my thumb and I can quickly loosen the blade, slide it in or out and re-tighten that blade with just one hand. The blade is also really easy to change and the yellow body is a nice size and fits well in my hand. The only thing this knife does not do is store extra blades in the body. But, I do not mind that since the replacement blades come in a really nice plastic case that is easy to carry in my tool belt. I have had two of these knives over the past 5 years and will get another one when my current one wears out (or I loose it...again).
