    I find it depends on what you are cutting;

    Straight bit - best with a blade and ruler

    Curved bit - scissors are probably best

    A really sharp blade helps and a good pair of scissors a must.

    Like most things in life you tend to learn from your mistakes!

    When I first started this hobby I used scissors all of the time. Now I use a hobby knife almost all of the time.

    For straight cuts I use a straight edge like a metal rule. I usually free hand the curved parts, cutting slowly and leaving the point of the blade in the paper and turning the page when needed to cut around the curve. That technique usually produces a smoother cut. :)

    Thank you!
    you have picture of the knife metal rule?

    The knife has a soft handle.

    One rule is a flat metal rule with a cork backing.

    The single rule has a channel for your fingers to protect them from the knife and two rubber strips on the back for non-slip. It is made by Helix.

    Did it take long to get used to that knife handle? It looks like it would be abit awkward to use compared to the usual round ones.

    Didn't take long at all to get used to using that handle. The curved top and slightly concave sides provide good control areas and support for the fingers and thumb. It is soft enough so it does not hurt the digits. It is made by Fiskars. :)

    Some time ago I made a tiny lesson about cutting....


    Cutting seems to be fairly easy don't you think.....
    Yes it is,if you do it right.
    When I started papermodeling I just jumped into it with absolutely no knowledge at all about a few years back.
    I bought a knife......useless
    I bought some scissors.....useless
    I got myselves a plastic ruler....useless
    I had some glue at home....useless
    So I ended up with making a mess out of my first model that was a huge C130...ment for advanced builders.

    But back to the subject....cutting.
    The basic tools are: A good scalpel type exel knife with blade #11 or similar.A pair of scissors of the nailcutting kind with a curved tip,and a pair of the same type with a straight tip.A metal ruler and tweezers.
    Here are the basic tools

    When we are ready to make the cut we want the light to be facing agains you.In that way we can see better without the edge of the ruler making a shadow covering the tiny outline of the part we are about to cut.
    So we place the ruler with only about half of the outline showing on the outside.

    The knife is to be held around 90degrees on the paper normally.The blade is very sharp so it's not neccessary with a lot of downwards pressure.

    Not all parts are suitable to use the ruler, so freehand cuts are very common where you don't want to use scissors.And when you gain more experience you often choose freehand cuts.
    Here is a shot on which side NOT to cut....Cutting on that side will make a shadow you don't want.A clear view of the line you are goiung to follow with your knife is vital!!

    Here is in my opinion the correct way to make the cut.Here you will have a clear view to the line,and can easy make corrections to your way down the line.We don't use a lot of speed here....but rather slow.I do most my cutting on freehand so I just use the metal ruler on longer straight cuts.


    Cutting round parts with a small diameter with scissors are not always a good idea.To have perfect control of the cut we use only the tip of the knife picking our way around the parts.I always moves anti clockwise in theese cases.In that way I have a very good control on where I punch the tip through the paper.

    If we look closely to the picture we can see the small cutmarks around the edge.Parts down to 1mm can be done this way.For larger parts I use the Olfa circlecutter

    When cutting inside a part the cut has to be made clockwise.The knife has to be held in a very uppright way to prevent the edge to cut into the part.
    So small cuts all the way here also.

    Hi Roni1234 and all
    To summarize, it's all depends on what more comfortable to you
    I use paper knive (the one that is called Japanese in Israel) for hard work - thick cardboard and wood, two types of Xacto-like knives (in Israel they are called graphic knives) - for thick and thin paper and two types of scissors.
    I know someone who uses scissors only and as you saw already there are guys that use knive only. It's all up to you/your habit

    Indeed... I'm one of those scissors-only people and I'm happy cutting this way, it's only a matter of personal choice. No tool is the best, it's all about how you use them ;)

    And great tutorial Johnny!!
